These were on display in Brooklyn at the City Reliquary. They may still be up. they're from the 30's or 40's. I've seen pictures, but hadn't seen one of these in person until last Sunday. Hard to describe the feeling that went through me when I imagined riding one of these behind a motorcycle at 60+MPH. Lots of amazing details on these bikes - I just stood there staring at them for quite a while, and hated to leave. No, I don't want to ride one.
