Since the dawn of time, card manufacturers have been cheap and lazy. You know it. I know it. They know it. Back in the day, film was expensive. not to mention paying the dude taking the shots. So they decided to be pro-active and recycle. You had no idea card manufacturers were so pro environment, did you? (Let's not mention renting barges to carry out thousands of unwanted cards to be dumped in the ocean. We'll consider that a man-made reef)
Anyways, Topps and OPC have been re-using images for ages. Even when the image in question no longer had anything to do with the subject.
Case in point. The year is 1976. The NHL is in minor disarray as a few teams change cities, names, players, etc...
The Topps version on the left shows us that there is nothing to see here, everything is A-Okay. Denis Herron still plays for the Kansas City Scouts. OPC, Topps' Canadian brother, knows that will never fly for the all knowing hockey connoisseur that we all are right out of the womb. So OPC gives us his new team name, logo, and a small blurb explaining why the uniform does not match the information given. They do not, however, give us a new picture of Denis. Nor do they alter the old one. Sometimes simple is best.
While helpful, this does not tell us the whole truth. There is no team in Kansas City anymore. The Scouts have relocated to Colorado and become the Rockies. Again, the Topps card on the left makes no mention of this. They would have you believe everything is kosher in the land of ice and rubber.
