Any vintage racing experts out there?
 

I'm trying to identify this autograph. It is on a program for the 1953 Rex Mays Classic.

I was able to identify Bob Scott, Jack McGrath and Bill Vukovich pretty easily but I'm having trouble with this one.

Figured it out. It is Manuel Ayulo. Both he and Bill Vukovich died as a result of accidents at the 1955 Indy 500.
