Just acquired from Republicaninmass....don't have it in hand but pretty excited to add it to my signed 1957 set. Already had a Giants team card signed by Hoyt Wilhlem and one by "Red" Schoendienst but this was unique enough that I couldn't pass on.
After his playing career, Carl Hubbell joined the Giants front office as farm director in 1944 and stayed with the team until 1977.
