Here’s an incredible advertising contract featuring the full-name signature of “George H Babe Ruth.”
The fully executed agreement was signed by a representative of the National Broadcasting Company in March 1939, and states the final terms for what I guess was the severing of the relationship that had provided for Ruth’s endorsement on behalf of Red Rock Bottlers, Inc.
You can see that the EX/MT document came with a PSA/DNA certification. It was auctioned off in December 2004.
