Kennt jemand Karten/Quellen, die monumentale Kunst aus der DDR zusammenstellen?

There are a few books about it like ,Kunst am Bau in der DDR‘ or ,Baubezogene Kunst. DDR’. It has become a bit of a topic in recent years…or let‘s say the ,Ostmoderne‘ in general.

Edit: Also a professor told me that a friend of hers is collecting pictures and stuff at the moment to late publish it. I am doing my architecture master in the east of germany, it’s a topic there and the reason why i also did a bit of research on that topic.
