Not much of a Tigers collector but did pick up this 1939 Tigers signed ball at an estate sale in Dallas maybe 12 years ago for $30
The tag just said "signed baseball (?)"
Signatures aren't bold at all. Hank Greenberg's is very faint across the sweet spot. I recognized Chas. Gehringer and Rudy York and knew it was a 1930s Tigers ball so I bought it. I wasn't able to identify the year until I got it home and looked up the names. HOF Earl Averill is also on this one.
