hello wehrhere - don't know about being recognized...He and his family has always owned one of the largest galleries I have ever seen (as a child), and they were extremely well to do. In 1956/57 they drove a large Cadillac, and I think they also had a driver with that. I know, because their daughter and I went to the same boarding school, and one time, I drove with them.
The gallery is still there, the daughter Catarina now runs it. The pieces are copper prints, therefor all originals. check the website www.geissendoerfer.de
Their Gallery is prominently located on the market place in Rothenburg o/T - and the most desirable real estate in town.
