Schwerte estate, since over 40 years untouched collection "all world" in 3 old printed form albums. As well the Europe volume 1 (Schwaneberger Rind from short post-war) well-stocked by Russia / Soviet Union with Airmail and Zeppelin issues, Turkey with many overprint values, over the Ukraine pending Hungaria with amongst other things the Zeppelin overprint issue from 1931 (Michel no. 478-79) on the with the LZ 127 transported 2 "Behrens" covers. The two of them oversea volumes not quite so rich in substance, but surely also with interesting values, on itself designed album pages.
