I found this a great delight when I first open it, and continue to be delighted by it each time I do! 1920s German, with "Toilettez" embossed in gold on the front, I believe to suggest it would be a pocket mirror held inside. (Translation is basically "you groom.") But instead of your face, here this clown, whose eyes roll and big red tongue extends incrementally as you open it, until that tongue is all the way out. Great graphics and good fun!

 3 9/16" x 2 1/4" closed. Excellent condition and fairly scarce; I've found a couple example of these out there, $50-100.
