It's wild how the most 'important'
(and most collected) card of them all,
Roberto Clemente, is virtually always off-centered top to bottom. I haven't seen such a
regular occurrence with any other card in that set.
(Obviously not scientific, but) here is a screenshot of consecutive graded listings on
eBay right now, all with the same
'inherent lowness'...

If you ever find a
truly centered one,
(to bastardize 38 Special) hold on tightly!!!!
