1944 "Poczta Powstancza Warszawa, Sierpien 1944" and Polish Eagle handstamp on front of a sheet of white paper (folded in half). This handstamp was prepared during the first days of Warsaw Uprising at the AK Field Post, ul.Szpitalna 4. Discovered in 2007, this item was the subject of an article by Zbigniew Mikulski "Najrzadszy list z Powstania Warszawskiego" (the rarest letter from the Warsaw Uprising) in "Filatelista" (9/2007), v.f., signed Petriuk and Korszen, with their certificates, each confirming this to be the "only known" and one of the most significant philatelic rarities from the Warsaw Uprising (Image)
