Old kellogs display.

I live on an old farmstead and we unearthed this display last spring. It was hanging in the loft of what I think was the old summer house. We had been in the loft many times but this piece went unseen. I cant remember what it was that drew us to finally see it but I'm glad we noticed it. Ignore the junk that I have on it and I think its a great find. I cant decide if its from the 30's or 40's what do you guys think? Thanks and happy hunting!
