Man in Moon cup?

[mary cay]

This cup was given to me by my Grandfather when I was born in 1943. I have only seen one other, in an antique store, I bought it for $5.00. I know nothing else about it other than this. I hope someone on here can help me out. Thanks.

I don't know anything about it but it definitely has a real 1930's look. What does the mark on the bottom read?
