Warsaw Uprising - Home Army field post (Poczta Polowa AK) - First definitive issue. 

Soldiers of the Home Army. 5 stamps issued 3 September 1944. Colors of stamps represent five different quarters of the city during the 1944 Warsaw Uprising. The series has been described in the Fischer's catalog (Fischer vol 2 113-117). These are very rare stamps that tend to reach high prices on various auctions. Here we intend to sell it for about a third of an average realized price on other auctions since 2008.
