Record Setters 1924

Here are five top drivers of the 1920s. I am all be certain this photo was captured at the Altoona board track in 1924.
From left to right:  
Ernie Ansterberg
Joe Boyer
Tommy Milton
Peter DePaolo
Harry Hartz
 
Actually, it's a stretch to call Ansterberg a top driver. He had a brief and undistinguished career. The others are hall-of-famers.
 
Thanks to the Paul Sheedy Collection for this photo.
