No, this is not an early look at the 2010 Upper Deck baseball card design.
In fact, this is Topps' solution to the Braves moving from Milwaukee to Atlanta. It appears that Topps didn't have a photo of Mathews in an Atlanta hat so they decided to just airbrush the old "M" off his cap.
When I first saw this card I thought a kid took an eraser to it. But as I looked closer I realized that Topps did the erasing for him.
It's too bad because it looks ridiculous. I would rather have had him in the Milwaukee cap. I think that if I were a kid in 1966 I would have been able to figure it out.
At the very least this card gives us an idea of how difficult it will be for Upper Deck to make cards of major leaguers without using team logos. Since the company lost its license to use the logos yesterday, it will have to get awfully creative in its design to satisfy today's baseball card buyer.
