While on the subject of Berlin - I have several ink-reproductions (lithos, I think) of photographs made of Berlin and surrounding areas. They precede the introduction of the automobile. And while it is all very early in the technology of photography, the work is the best I've seen. I would be happy to put them up on a web site if anyone is interested. I'd be very interested in seeing photographs of the same areas today, and to learn more of the history of the areas. (The architecture was beautiful. I know much, perhaps most, has been lost to wars.)
