There's an interesting item on the backs of the cards.
This is what they look like. Check out the cartoon.
Like the cartoons on the base cards, this one has borrowed from the 1970 set. But it was altered too.
It comes from Woodie Fryman's card.
Check out that big tobacco leaf.
And now the leaf has become a jersey. I did look to see if the jersey was taken from a 1970 card but couldn't find it. I'm going to assume that a Topps artist drew the jersey.
