Thriftstore find---Print

I found this print at the local Goodwill today for $5. I THINK it might be a silkscreen (restrained use of color, blockiness of shapes etc). It is not signed. The frame is a cheapie. I picked this up and put it down a few times. I figured for $5 I would give it a try. Isn't it funny about prints, they can be so inexpensive but the framing gets expensive.

I got it home and am glad I decided to buy it. It might be signed behind the matting.
