Hans has been kind enough to contribute a number of photographs of Van Veen motorcycles and some history of the extraordinary rotary-engined machines, along with images of other European and Japanese classics, among them H1 and H2 Kawasaki, MV350 Twins, Benelli Twins and the truly exotic Bimota.
His site contains a wealth of information, but at time of writing (Jan 2011) it is only available in Dutch. It's a very nicely presented Flash site, and is well worth a visit.
