This was an exciting project...after having our print person create a baseball diamond background in the needed proportion we laid out these collectible cigarette baseball cards into their player positions and attached with acid free clear photo corners. The client had enough to do this two sided with museum glass on the front and clear acrylic plexiglass on the back. The cool thing about these cards are they are folded and when you unfold them there is a different player on the inside. This is why some of the cards are taller than the others when opened!
