Help with Honus Wagner Sporting Goods signed ball
 

Wondering if I can get help with identifying signatures on this bonus Wagner sporting goods ball. A couple are pretty legible smoky burgess and moose skier on. I also think one is yogi Berra. Ball probably originated from Pittsburgh area but trying to figure why there are Yankees on it. Maybe if some can identify the others it can be figured out. Thanks for your help.

Looks like Gil McDougald.

Maybe someone had it signed during the 1960 World Series. That would explain why there are Yankees and Pirates on the same ball.
