I have seen German glass clown ornaments similar to this, but never in such a miniature size. It's barely 2-1/2 inches tall. The little clown has a flesh painted face, his hands in the pockets of his rainbow tinted suit, his head tilted just a bit. There is slight loss of the inner silvering and some crazing of the face paint. The ornament dates to no later than the 1950s, possibly earlier.
