S.F. Giants Pinback Question...

[andypcl]

As a Giants fan, I had to take a chance on Ebay with this one. Can any button guys (or Giants fans) shed any light on this pinback? It's 4" and looks to be 60's era. I haven't a clue as to whether it may have been a vendors badge, stadium souvenir, etc...
Thanks,
Andy

Andy,

I have seen this design once before for a pin, Red Sox, L-g-30 in my book. I would date it from the early 1960s. Not sure if it is a vendors pin, but its shape/size would suggest it was intended not to be collected as a momento as much as worn.

All the best,

Paul

Thanks very much Paul. I have your book but didn't think to look for the design throughout the other team pages.
