Moderately toned baseball which is almost certainly an official American League or National League example (stampings faded) having been signed by a total of (23) players including eleven Hall of Fame members. Signatures include Babe Ruth, Jimmie Foxx, Mel Ott, Johnny Mize, Dizzy Dean, Lefty Gomez, Gabby Hartnett, Luke Sewell, Frank Frisch, Ernie Lombardi, Joe McCarthy, and MLB Commissioner Kennesaw Mountain Landis. Signatures range from 6-9 out of 10 with most rating 8. The ball was signed at the 1937 MLB All-Star Game played in Washington D,C. and is notated as such in period fountain pen across the sweet spot in unknown hand. Very fine combination of Hall of Fame players to include the first three members of the vaunted 500 HR Club (Ott, Foxx, and Ruth). The baseball originated from a prominent Birmingham, AL autograph collector in the 1930-60s period, Dick Clark, and includes printed news paper article of corroboration. Includes full LOA from PSA/DNA (Ball: VG-EX 4, Signatures: NM-MT 8, Overall: EX-MT 6)
