1939 Minneapolis moline advertising clock

I found a 1939 Minneapolis Moline promotional advertising clock. It was up in an old garage behind a old building I bought. The clock hasn't seen the light of day for probably 50 years. I'm assuming its very rare because that i know of nobody has one. I have searched the net for hours and now i'm calling and sending emails trying to figure out what to do with it.

Thanks for the help
