Greg and Steve identified the East German stamps and I've included them in this complete list. However I could be wrong but I think the 30pf, 40pf, 50pf and 70pf stamps are the later ones from 1959-60, because the 1953 versions should have the imprint "E. Gruner K. Wolf.", which I can't see on these.
