The posters became part of the German Historical Museum's collection in 1990 after the 1989 fall of the Berlin Wall.
Peter Sachs has said he only learned of the existence of the collection in 2005, and began fighting then for their return.
When he receives the posters back Sachs will repay the compensation that his father received, Druba said. He said it was not yet clear what the amount would be in current terms.
