I have an autographed baseball from the Atlanta Braves in the 70's? - atlanta baseball camps

I have signed a baseball Atlanta Braves, but everyone knows what year it is. Some of the names that I read Larry Owens, Rick Camp, Brook Jacoby, Gene Garber, and Randy Johnson. Can someone tell me, the computer or go directly to me to find out. Braves.com I have tried without success. Thanks
