1991 Upper Deck Pedro Martinez Rookie Card #2F - 2 Hologram Error/Variation - Rare? This card has two holograms on the back; one full that's placed lower than usual and then half of a second hologram along the top. I tried researching error versions of this Pedro card, but didn't come across any. Also didn't see any references online to any 1991 UD cards having two holograms. Not sure how rare it is, or really what the value might be. The card does have an imprint across the middle which I tried to illustrate in the photos but they didn't pick it up very well. Not sure if it's an imprint related to a process that would lead to two holograms or if something happened to it while handled in the years since. Please let me know if you have any questions on it. 

Please see photos for exact item(s) and condition. All item(s) shown in photos included. Will be securely shipped in a bubble mailer. Happy to combine shipping on multiple items.
