The original note where our Fritz Neumann confirms that he is Ric, published by Mark Strong of Meibohm Fine Arts included an address:
His address is Gartenfelder Str. 132 h in Berlin Haselhorst.
Since Torsten Steinberg, the author of the ad mentioned in the last post
wrote about the old address books of Berlin
I tried to do the same. This are the results, the first result was from 1934:
Above only random samples, therefore the cut-outs are not continuous. No address books are available after 1970, so here are some extracts from telephone directories.
This at least makes it clear that our Fritz Neumann lived and worked in Berlin for around 50 years. And perhaps died in 1984, or at least stopped working as a graphic designer, e.g. because he went into an old people’s home.
