1937 New York Yankees team-signed baseball featuring the signatures of Lou Gehrig (sweet spot), Joe DiMaggio, Tony Lazzeri, and manager Joe McCarthy (sweet spot). This ball was originally obtained at spring training, as noted by the vintage blue fountain-pen signature on a side panel that reads "From Uncle Jim - St. Pete Fla. - to David - 3/20/37." In addition to the signatures of Gehrig, DiMaggio, Lazzeri, and McCarthy, the ball has been signed by sixteen additional team members. However, PSA has deemed all the remaining signatures to be "clubhouse" versions (a common practice at the time). The "clubhouse" signatures featured on the ball are those of Ruppert (team owner), Gomez, Pearson, Wicker, Schulte (coach), Koy, Chandler, Makosky, Fletcher (coach), Dahlgren, Crosetti, Saltzgaver, Heffner, Sundra, Tobin, and Tamulis.  The signature of Al Schacht (the "Clown Prince of Baseball") has also been deemed a "clubhouse" example by PSA.  A few of the signatures display slight smudging, but overall they grade a strong 8/10 on average. The Spalding "King of the Diamond" baseball has been coated with a thin layer of protective shellac and is otherwise in Near Mint condition.
