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.

GOT YOUR E-MAIL ,I HAVE A TEN CARD SHEET OF THESE,THE NO.11 MIKE TEETER,AS IN THE EXAMPLE…THIS WAS A BUNTCH OF SHEETS A PROMOTER HAD PUNTCHED TWO HOLES AT THE BOTTOM OF AND PUT BINDER RINGS IN…THE REST ARE IN GREAT SHAPE…AS SOON AS I CAN I WILL SEND YOU A SCAN…
I DOUBLE CHECKED THAT SHEET I SAID I HAD….YOUR REFERING TO THE TEXT MISSING FROM THE LEFT SIDE …PART OF 1989 AND SOLOS THE WORD PRESS MISSING?…NONE OF MINE HAVE THAT…SPOKE TOO SOON…
Not to sound naive… but does a simple printing error like this really qualify as a legit “variation” ? Many old cards have those annoying ink blotches. Are they really “variations” ??
