World Series Strikeout Records Signed Baseball Sandy Koufax Bob Gibson Carl Erskine 1/1 PSA

World Series Strikeout Records Signed ONL Baseball w/ Sandy Koufax, Bob Gibson & Carl Erskine from the Personal Collection of Carl Erskine.  Includes PSA LOA.  This is a unique ball that Erskine had signed specifically for own his personal collection.  It's the only one like it on the planet!  

Each player signed the ball and inscribed the date of their record, the total number of strikeouts they had and the team they played against.  Coincidentally, each game was pitched on October 2nd.  Erskine notated the theme on the sweet spot. Gibson still holds the record today. 

The Provenance from Erskine is awesome.  He talks about how he obtained the signatures of Koufax and Gibson while attending an event together.  He mentions that this ball is his only possession that commemorates his World Series record. And finally agrees to sell the ball for $1,500 back in 2012 and will use that money to have a ring made of the record.
