1939 would be the absolute earliest, given the size of the backboxes, but the arcade would need to have just been setup with all brand new machines that all had that new shape/style.
Most like 40s to have that kind of variety of the full-sized machines.
It's OK, someone pointed out that the Queen's Gambit had a shot that was supposed to be a 1960s drug store that feature a 1990s comic on one of the racks! tsk tsk
