The 1986-87 O-Pee-Chee set flip-flopped the photos of Vancouver Canucks left wing Moe Lemay with that of Calgary Flames center Joel Otto. This was Lemay's last card, and Otto's first card. Every time I would look at my set--which is in pages-- I would get annoyed that these two cards were messed up. At the right you can see what the erroneous Lemay card looked like--it even says "Now with Canucks", trying to justify why a Flames player is on a Canucks card. Using Photoshop, I scanned both cards and digitally put the correct photo on each one. I then printed them out on high-quality glossy photo paper, and carefully cut them out. Finally, I put these "corrected cards" over the "error cards".
Well, it's not like O-Pee-Chee was going to correct this mistake 20 years later.
I have also revised Joel Otto's card.
