Here are a few of his works. I'll be posting more in coming days.
Commuters waiting for south-bound trains, Chicago, Illinois, 1941
Here's what I love about this photo: on lower left is seen (rather dimly) a chain-link fence, and on upper right the shadow of that fence stipples the top of the train. Brilliant artistic framing in this photo.
Girls on main street, Watertown, Wisconsin, 1941
Striking realty workers, Chicago, Illinois, 1941
In the last photo I love that the group of strikers is multiracial - definitely progressive for the times. It looks also as if there is a group of women pickets on the far right of the photo, so it's truly an inclusive protest!
