Proofide, that's a heck of a photo!

Derailleurs were a French thing. They were popular in France earlier than in other countries, particularly the UK and US. I don't think the internally geared hub (IGH) ever caught on in France. Neither did coaster brakes.

I think the lack of je ne sais quoi is because this subject actually rode her bike. Those models in those pictures often look to me like they don't even know how, so their poses are unrealistic, to say the least.

Those shoes are amazing, but I know very little about fashion. I didn't know such shoes existed so long ago. I thought they were a 1970's invention. It just goes to show, everything old is made new again.
