Weird 1967 Willie Mays Anomaly(?)

[JollyElm]

Something is rotten in the state of Denmark...

A while back, I showed how a few 1962 green tint numbers 'always' appear thinner than normal, and it was clearly due to the cutting process at the factory and not a mass trimming operation undertaken by collectors from all across the country (LOL). Well, recently I was looking at a decently priced 1967 #200 Willie Mays card and I saw it was swimming in the PSA holder. It was way short side to side, and that gave me great pause to buy it. Perhaps someone PWCC'ed it?? I dunno, so I began looking at all the PSA versions of the card on ebay (none of these are mine and I have no idea who is selling them), and to my great surprise I saw that the vast majority of them (clearly over 90%) were short side to side. The amount of space varies, but the same anomaly occurs across all grades. Does anyone have any insight into this situation? (Assuming the PSA slabs are all the perfect size) If the cards were all cut thin, then other cards in the Mays column/row should suffer from the same malady. I haven't looked into it.

These screen grabs might not be large enough to clearly tell, but every single one of them has the card definitively short side to side (and this was just a quick ebay and auction prices realized search, not an in-depth investigation whatsoever)...
