I am writing an article about a Norwegian architect. She herself has written in a short biographical text that she was in Berlin in 1931, while the INTERBAU exhibition was arranged. (She is dead, so I cannot ask her directly) 

I have never seen the acronym INTERBAU used before the 1957 exhibition in Berlin, so I think she mixed things up here, but I am not quite sure. I have not found INTERBAU in connection with the 1931 Deutsche Bauausstellung in any journals, databases or websites. Can anyone confirm that INTERBAU was first used for the 1957 event?

hoping to hear from you, and wishing you all a fantastic and sunny Easter!

All the best from Trondheim, Norway:
