In the late 19th and early 20th century, paintings of anthropomorphic cats graced the front of holiday and general use postcards. You could find postcards of cats writing letters, packing suitcases, delivering flowers and waiting for Santa Claus. In fact, artists painted images of felines doing just about everything. Though the names of the artists are too often absent from the postcards featuring their work, their illustrations haven't lost their charm with the passage of time. To see additional examples of anthropomorphism, visit our galleries showcasing the paintings of artists Louis Wain and Maurice Boulanger.
