Hi Mike,
Happy holidays! Congrats on this cool Clemente pickup.
I'm certainly convinced by your evidence that it is the real deal. The photo matching of so many elements of the event really lock it down for me.
From what I recall, and after doing a photo search, I do not see evidence that Stargell used a batting glove when hitting. You obviously have a wealth of knowledge about your Buccos. Did he ever wear a batting glove when hitting during 1972? He certainly had a habit of wearing a batting glove on his mitt hand when playing 1B. See photos of him hitting and playing 1B.
If he was seen in the on deck circle wearing his batting glove in other photos of the moment, why would he take it off again prior to hitting?
I suspect because he wore it on his glove hand when playing defensively at 1B and took it off prior to the AB in the on deck batters circle. Maybe it was his usual routine, or he was so focused on Clemente's milestone AB that he forgot that he was still wearing it. I guess we will never know...
In any case, congrats once again.
Definitely an epic pickup for your Clemente/ Bucs collection.
