I know some of you enjoy finding vintage variations and I ran across one while doing my work on the 1962 green tints. In my book, I wouldn't really consider it a variation, but there are other guys who collect EVERYTHING, so this may be pertinent to you.
On the Babe Ruth Special card #135 (non green tint version), there appears a stray hair next to the 'A' in the caption. In looking at ebay and other places, I ran across 3 or 4 of them, so it's not a one time thing. But it appears in only a fraction of the cards, so it is definitely rare, for whatever that's worth. The hair must have been on the final paste up of the layout before it was photographed and turned into printing plates. The only other difference I found between the two layouts is that the black caption in the yellow box of the 'hair' card appears a little lower than in the 'normal' version. That could simply be a printing anomaly of the black plate or it may be a true differentiation between the two versions.
I dunno, but here it is...
