Vintage note card set from The Metropolitan Museum of Art featuring a charming collection of cat-themed artwork. This boxed set includes four distinct designs: "The Favorite Cat" (hand-colored lithograph by Nathaniel Currier), "Kitty" (hand-colored engraving by George White), "Black Cat" (painting by Chu Ling, Ch'ing dynasty), and "Cat" (painting on silk by Toko, 19th century). Each card provides historical details about the artwork on the reverse side. The set comes with matching cream-colored envelopes, perfect for correspondence, art lovers, or feline enthusiasts. The outer box shows some vintage wear and light spotting, but the cards themselves remain in excellent, unused condition.
