This outstanding ball has 17 of the 18 members who were living when this incredible team was named in 1999. This ball started as an OAL Ted Williams single-signed on the sweet spot. The sixteen other signatures were tediously collected and include Hank Aaron, Warren Spahn, Roger Clemens, Brooks Robinson, Willie Mays, Nolan Ryan, Johnny Bench, Stan Musial, Pete Rose, Cal Ripken Jr., Bob Gibson, Yogi Berra, Mike Schmidt, Ernie Banks, Mark McGwire and Sandy Koufax. Only Ken Griffey Jr. needs to be added to complete this amazing autograph collection which is near impossible to replicate. Ball is NM. Signatures average 8/10 except for Schmidt and Rose, which are faded.
