Here is an old image from the lone copy of this variation I have owned. No longer a part of my collection, I still flip over the backs of the World League inserts in 1991 Pro Set just in case there are other similar variations to be found. I do believe that there is much to still be discovered in 1991 Pro Set and the World League sets.
Although I have only found the one copy, it’s scarcity is yet to be determined as few collectors know of it’s existence and bother to check for it. Hopefully, with the word getting around on this variation, we’ll see more copies for sale and possibly new, similar variations in the World League subsets.
