Courtyard of an apartment building on Hochedlingergasse not sure which one.

This picture was taken by Joe Weiss during a trip to Vienna. He said, that this was, 29 Franz Hof Ling Gausser (street) and that the bakery was in the front. The bakery was actually at Franz Hochedlingergasse 24. This was not the back of the bakery. It might have been the back of another apartment building that one of the brothers lived in or maybe back of Karl Koppel's apartment. Note that Abba never lived in Vienna. He was born in 1938 in Zagreb and the family fleed to America in 1940.

You can see a video of the back of the bakery from July 2022 when Naomi and I went.
