Help verify a 1956 variation?

I'm with you ALR. I always thought anytime the printing press process got messed up, it was human error. When they changed something on purpose, then we are talking about a variation. The 1956 team cards come to mind. Some have the dates for example and some don't. That is a variation. Or the 1973 manager cards, where they changed the backgrounds on some of the small photos. That's a variation. If a printing press breaks and causes a letter to be missing, that doesn't seem like a variation. It's a malfunction. They can be interesting, but I certainly wouldn't include it in the "master" set. They had several cards in the 1981 Fleer set that had a random hair on the printing press that happened to look like a hand. I never thought that was a valid variation, but people were chasing them. Other opinions are certainly welcomed, but that's my opinion on what is a valid variation.
