The steel Diamant is very interesting.

I recently received this photograph of a Viennese architect's collection:

I did some Googling and found that this architect has a website, and it is very nice indeed. It has individual photos of all of the bikes in the collection - at least a hundred - most of which are on topic. There are tons of relatively unknown marques, which makes this a very unusual collection. And the bike pics are organized by frame material, so you don't have to look at any offensive off-topic bikes if you would rather not.
BTW, the site has a very cool feature: click on any of the individual pics and a moveable close-up window will appear, the likes of which I've neve seen before.

Enjoy.
