1990 Bowman Lithographs

I was searching through my flat file and found a bunch of these signed and numbered 1990 Bowman giveaways (I think?). Can't seem to find any prices on eBay. Anyone collect these or know if they have any value? They're actually kind of cool.
Unfortunately I don't have the Ryan or Mattingly.

In the 1990 Bowman art set (depicting the lithos you have) that were inserted 1 per pack, a variation exist on the back of the Dwight Gooden card, where the "$100,000" prize value is missing on back.
It basically reads:
"This card could be worth _________________________"
Collecting Robin Ventura and Matt Luke.
Raw: Tony Gonzalez (low #'d cards, and especially 1/1's) and Steve Young.
