The artist is Eugen Hartung (1897 – 1973). He painted many dressed cat pictures, which were published by Max Kűnzli in Zűrich, Switzerland. After WWII, these were published in the United States by Alfred Mainzer, Inc. of New York. This is an original Swiss offering, a lithograph (not a screened print), with the unusual deckle edges. This was a fun research project for me. I’d never heard of these cards before. Any comments or corrections will be appreciated.
Note the boy cats in the windows laughing at the girl cats. And the artist’s signature, which should have been in the lower left, has been cropped out.
