Actually, I discovered this variation in the summer of 1976. I was a 15 year old baseball card collector and a columnist for Sports Collectors News. I had a column called "Randy's Ramblings"
Well, I was reading some of my old columns tonight and I ran across an interesting article I wrote about the sheer number of baseball card sets issued in a year. 1976. There was over 30! LOL. That was a lot back then.
I was very into errors and variations back then, always searching for them.
The variation is: #85 Billy Grabarkewitz, comes with a red sun or a yellow sun. Very distinct colors. The yellow is much harder to find. Here is a copy of my article from 1976 and links to both variations found randomly on Ebay.
Somehow this was never cataloged in Beckett, SCD, or anywhere else and I had totally forgotten about it. Have at it boys!
