Photos of early garages are very interesting if you study the contents. Here we have a Center-Door Model T and a Harley-Davidson with its sidecar detached. These vehicles might date the photo to the mid twenties. The overhead shafts and belting might have powered a lathe and a drill press over on the sidewall. There is also a quite deluxe 8-day regulator clock up on the wall over the bench.
The one thing that is very different from today are the big windows for light and what possibly looks like a sky light in the top left of the photo. Back in this time electric lighting was sparse and natural day light was what most people worked by.
