I have seen many is this type of Joe Jackson threads asking if it is him. To me this RPPC looks like a perfect ringer for Christy Mathewson. Tha stance and the grip are identical. I wanted to come on here to get everyones opinion before I listed it for sale at the low price of $500,000.00 with a best offer option.
Yes I know the RPPC actually dates from the 1904-1918 era but facts have not stopped similar inquiries before.
Thanks in advance for any help.
