How to identify an authentic Cassatt print—and avoid counterfeit reproductions—when buying online

The distinction between original prints and reproductions

Mary Cassatt’s original prints are drypoints, aquatints, or soft-ground etchings executed between 1878 and 1925, primarily in small editions of 25 or fewer. These are not to be confused with posthumous photogravures (e.g., the 1960s–70s Hiroshi Nagai prints of her work) or modern offset lithographs, which lack the tactile quality of intaglio plates. The Metropolitan Museum of Art’s Heilbrunn Timeline of Art History notes that Cassatt pulled her own impressions, often adjusting ink density by hand—visible under raking light as subtle plate tone variations.

Posthumous editions authorized by the artist’s estate (such as the 1970s–80s etchings reprinted by Arts Magazine and documented in the Breeskin catalogue raisonné) bear blindstamps or estate stamps. Unauthorized reproductions, by contrast, are typically mass-produced on smooth, high-gloss paper (120–170 gsm wood pulp) and lack embossed chopmarks. Christie’s Prints & Multiples department reports that fake Cassatt signatures often use blocky, inconsistent script, whereas her authentic monogram—a conjoined M and C—is fluid and slightly slanted.

How to verify provenance and edition authenticity

Every legitimate Cassatt print should trace to one of three sources: (1) a lifetime impression listed in the Breeskin (1979) or Mathews & Shapiro (1989) catalogues raisonnés; (2) a posthumous edition approved by the Cassatt Committee (e.g., the 1980 Mother and Child suite, limited to 150 impressions); or (3) a documented exhibition history, such as the 1998–99 retrospective at the Art Institute of Chicago. The IFPDA advises requesting a certificate of authenticity that specifies the edition number, printer, and ink type (e.g., “black ink on laid Van Gelder paper”).

Avoid sellers who use terms like “museum-grade” or “archival reproduction” without citing a catalogue number. For example, a genuine Maternal Caress (1890–91) drypoint will reference Breeskin 127 and measure ~24.8 × 19.7 cm (9¾ × 7¾ in) on the plate; a fake may alter dimensions slightly (e.g., 25 × 20 cm) to evade detection. Sotheby’s Prints specialists note that Cassatt’s estate authorized only two posthumous printers: Atelier 17 (for intaglio) and Pierre Chave (for lithographs).

Material and technical red flags in counterfeit prints

Cassatt’s original prints were pulled on laid or wove papers with deckled edges, typically 250–300 gsm cotton or linen rag. Modern fakes often use bright-white, machine-made paper (e.g., 200 gsm alpha-cellulose) with artificial aging (tea-staining or laser-distressed edges). The Tate’s Art Terms glossary distinguishes true giclée prints—pigment-based, sprayed on archival substrates—as a contemporary medium irrelevant to 19th-century intaglio; any Cassatt labeled “giclée” is a reproduction.

Inspect the ink: Cassatt’s etchings employ oil-based inks that darken minimally over time, whereas offset lithographs use synthetic inks that yellow or crack. A 1902 The Bath aquatint (Breeskin 154) will show granular texture from the resin dust; a fake will appear flat, with halftone dots visible under magnification. Glossy finishes are anomalous—Cassatt favored matte, uncalendered surfaces. For family homes, matte reduces glare but requires UV-protective glazing (e.g., 99% UV-filtering acrylic) to prevent fading.

• Paper: Originals use laid or wove rag (e.g., Van Gelder Zonen); fakes use smooth, bright-white wood pulp.
• Ink: Oil-based, with plate tone variations; fakes use uniform synthetic ink.
• Edges: Deckled or torn; fakes often have guillotined edges with faux distressing.
• Size: Plate marks measure within 1–2 mm of catalogue dimensions; fakes may scale incorrectly.

Where and how to purchase with confidence

Buy only from IFPDA-member dealers or auction houses with dedicated prints departments (e.g., Christie’s, Sotheby’s, Swann Auction Galleries). Prices for authentic lifetime impressions range from $8,000–$50,000 USD, depending on rarity; the 1891 Maternal Kiss (Breeskin 134) sold for $42,500 at Sotheby’s in 2021. Posthumous editions (e.g., the 1980 Mother Playing with Child) trade for $1,200–$3,500 USD. Avoid platforms mixing originals with reproductions (e.g., “authentic Cassatt print” listed alongside hiroshi nagai prints of her work).

Request condition reports noting foxing, plate wear, or in-painting. A legitimate dealer will provide high-resolution images of the verso (revealing watermarks or collector’s stamps) and raking-light details (showing ink texture). For framing, specify acid-free, 4-ply rag matting (e.g., Bainbridge Artcare) and spacing to prevent contact with glazing. Hanging height should center the print at ~145–150 cm (57–60 in) from the floor, adhering to the two-thirds rule above furniture.

Why the fear of fakes is justified—and how to mitigate it

The market is flooded with counterfeit Cassatt prints, particularly in the $200–$1,500 USD range, where offset lithographs are mislabeled as “limited editions.” Artsy’s Art Market report (2022) found that 18% of prints sold as “original” on secondary platforms were reproductions. The risk increases with popular subjects like The Child’s Bath (Breeskin 155), often replicated for baby shower gifts. To verify, cross-reference the seller’s inventory with the Cassatt Committee’s archive of authorized editions—no legitimate print exists outside these records.

If purchasing unframed, handle the print with nitrile gloves to check for plate impressions on the verso. A drypoint’s incised lines should be palpable; absence indicates a photomechanical copy. For framed works, request removal to inspect the backboard for labels from conservators or prior exhibitors (e.g., Wildenstein & Co.). Avoid “vintage” prints lacking documented chain of custody—Cassatt’s estate did not release unsigned impressions.
