hmmm...Beckett/Cardboard Memories are walking a thin line. Looks like they're trying to avoid copyright issues, but still have what an average collector would call a McDavid trading card. Upper Deck has an exclusive deal with McDavid as the ONLY prouducer of McDavid trading cards. So, legally speaking, Beckett/Cardboard Memories cannot consider this a trading card.
As to your question. It's more an advertisement than a promo. Even more a business card than a trading card. A business card the size, shape, and look of a trading card. But it's not promoting any trading card sets. It's self-promoting, or advertising, their business...Beckett Price Guides and the Cardboard Memories store. So, where would it be listed? Or should it be listed? Might want to ask Admin.
Someday my cards may double in value and then be worth half of what I paid for them.
