This flag is from the "Hungarian Women's Democratic Union" (MNDSZ) and is dated 1950. Made primarily of silk and improperly stored for 63ish years, it has many stains and small tears. It predates the Hungarian Revolution of 1956 and thus features the 1949–1956 Hungarian coat of arms, and was found alongside another flag (not pictured here) from the Hungarian Working People's Party. Based on the highly specific purpose of linking the MNDSZ to the Danuvia factory, I have no doubts that this flag is one of a kind.
 
53"X28" including multicolored fringe. Condition is clearly depicted in photos, a very rare flag with many flaws.
