1971 Baltimore Orioles autographed baseball
. On a Pacific Coast League ball.
Manager Earl Weaver on the sweet spot but off-center.
In 1971, the Baltimore Orioles finished first in the American League East, with a record of 101 wins and 57 losses. The Orioles also had four 20-game winners that season: Jim Palmer, Dave McNally, Mike Cuellar, and Pat Dobson.
Autographs are light but appear to include Jim Palmer, Brooks Robinson, Mark Belanger, Chico Salmon, Clay Dalrymple, Frank Robinson, Pete Reichert, Andy Etchebarren, Elrod Hendricks, Don Buford, Boog Powell and possibly Orlando Pena. Several other autographs unable to decipher.
The ball is in fair condition as it has a few stains on. Not authenticated.
