25 Cats Named Sam and One Blue Pussy by Andy Warhol, 1950’s.
"Andy Warhol loved cats, reputedly keeping as many as twenty-five in the Lexington Avenue apartment he shared with his mother. The book comprises sixteen lithographs of cats, each named Sam, and a seventeenth simply captioned ‘One Blue Pussy’. Warhol’s affectionate studies are full of whimsy, depicting cats in various postures of play and repose."
