Hello, I'm new to the site, hopefully writimg this im the right place. Ihave a unique hockey card. It's a 1991 score card. the front of the card is a picture of the 1990 stanley cup champipns Edmonton Oilers. but the back of the card is the back of card is #439 Martin Brodeur's first round draft pick card. i'm guessing it's a factory mistake. wondering if anyone has any info?. Or is this a really rare card to find. any info wpuld be great. thank you in advance.
