No history about baseball card and baseball memorabilia collecting would be complete without mention of the trade shows promoted by renowned promoter Gloria Rothstein and one of her biggest shows being the East Coast National Show held annually in White Plains, NY. Her shows helped shape the industry unlike any other.
Offered here is a rare autographed envelope decorated with a silk cachet of the legendary ballplayers who have signed from one of her shows; Mickey Mantle, Tom Seaver, Harmon Killebrew and Jim “Catfish" Hunter.
The signatures of these four National Baseball Hall of Famers are all boldly signed in blue ballpoint pen to present an attractive display for generations.
Excellent condition.
Authentication: James Spence Authentication (JSA) Letter of Authenticity and a Gotta Have Rock and Roll Certificate of Authenticity.
