I don't know how wide a scope of vehicles we're putting into the Big Year, but I find this cool, so I'm posting it. I've narrowed it down to '60s vintage, though all the examples I find online have Diamond T badging. I know Diamond REO became one at some point. Anyway, the model seems to be 931C, and the livery and all just scream mid 20th century and 'Murica.
