Topps used mug shots with the stadiums airbrushed into the background?

Or

Moganas rookie card photo shoot was going on at the same time?

Where was the Mack Jones shot? Maybe a cornfield in Iowa?? He does not have a stadium in the background.

Alfred Hitchcock was a guest photographer for topps .

[Brian Van Horn]

Shave and a hair cut two bits.

[BeanTown]

Fake 🎩 and bad shadowing

[Exhibitman]

I believe the Topps photogs were instructed to get certain characteristic shots; looks like a few of them got used here. Or they were all sitting for silhouettes.

Perhaps Don Mossi's cards should have used the mug shot approach

I asked a long-time Topps photographer where they kept all these types of images. He told me in the pro-file.

Probably a standard Topps pose, and one that inspired 1965 Topps Embossed, with all its profiles.

Also, shot was likely taken outside on a bright day and their hat brims would've shadowed faces, so the photog used a bright flash and shot from the side.
