Over on Old Cardboard it states, "Originally distributed with rounded corners and blank backs. Large stash found in 1980's with square corner variations." Does anyone have any additional information about the square cards? I am curious as to where someone found them in the 1980's and why thet are square instead of rounded. It doesn't seem that the square cards are considered reprints. I just picked up a square Ted Williams in great shape. I didn't pay a whole bunch (a tad more than $10), less than what I would have thought a Williams would command. Have I goofed? Thanks for any input. Mike
