need alittle input here but opened a few packs of 16 heritage and on the back of #28 freese card it sure looks like it could be a "gumstain" variation but have not seen it listed anywhere. Could it be just flawed printing on back of card? I have like 3 of them and only one has it on the back. Could topps have missed it? When I seen it I set the card aside like I do all varitions but can't find info so it's got me wondering...Anybody have any info or input on this card.. Would topps co. know? Bob (2card)
