The Perfessor, Big as Life

This 1944 photo of Brewers skipper Casey Stengel is up for auction at MEARS:

This photo, taken by Milwaukee's Grand Photo Studio, was used by the Brews in photo cards sold at the park during the 1944 season. The 3 1/2 x 5 1/2 inch cards had printed autographs and were sold for 25 cents a set through the mail and at the Borchert Field concession stands.

This particular copy of the photo has been altered for print, its background removed with correction fluid, the 1940s version of Photoshop. This is fairly common on surviving photos from the period.
