Nice collection of pre-war motorcycles by photographer Paul Clifton. These are more utilitarian looking than the overly designed motorbikes of the current era, but there's beauty in their spartan styling.
Lots of ideas here for vehicle design. I may be incorporating some of these into a future comic.
