I have had this Lou Gehrig painting that is framed for quite some time and at the bottom there is a stamp from the USPS from 1989. I have done some research about the painting and the artist is Bart Forbes, who has done paintings for some presidents and other famous people. The stamp by itself is said to not be worth much, but I am wondering about how much would something like what I have will go for?

I am hoping to sell it for somewhere around $30 - $50, but cannot find anything on ebay's completed listings (only the stamp). Any help would be great.

here is a scan of it:
