Here is a link to an eBay auction for the "picture" you have.

You call it a print. The auction calls it a lithograph. I'm not sure of the difference but I bet Sharon can explain it.
There have been other copies of this work sold on the internet. Prices are all over the place.
Regardless, it is a cool "picture". A great gift from some one to you.
