Card Manufacturer: Colla Collection
Card Set: Diamond Marks - Bookmarkers by Terry Smith
Card Number: NNO
Card Type: Base
These cards were inserted into packs of Diamond Marks Bookmarkers, And they fell one per 48 count box. You might recognize the art work from the 1991 and 1992 Fleer Baseball Provisions insert. The artist is Terry Smith, who produced a lot of art for Fleer sets in the 90's. You can see his website HERE.
The set consists of only 8 players and the Standard Catalog has these priced pretty high. The whole set books for about $50. Yeah I know, I don't put much value in book value, but it's just a guide folks. I guess falling one per box is a pretty decent hit.
