Roland Painting

I bought a rather wonderful midcentury painting at the show that came out of an estate in Phoenix. A large work, it depicts men with a crucible of molten metal in front of a foundry. I believe that it was painted in Pittsburgh.

The painting is signed Roland but I have been through all the Rolands on Artprice and Askart and don't see a real fit or match.

This decal is on the back of the frame, from the Jacobson Picture Frame Co. in Pittsburgh. The company was extant between 1943 and 1989. Thought about contacting them but they are unfortunately now long gone.

I believe this painting is early midcentury based on both the type font and the lack of an area code prefix.

Any help I can get ascertaining the author of the work would be greatly appreciated.
