Writer and illustrator Ruth Tzarffati both wrote and illustrated this tale of a beloved gold-colored hamster.
The text is in Hebrew so I don’t know the details of the story. But the illustrations are all kinds of retro good….*swoon*.
I went in search of some info on Ms. Tzarffati and found out she is a painter and sculptor as well and I found this very brief biography here (looks like the T was dropped at some point?).
