This is a Hitlerjugend (HJ) / Deutsche Jugend (DJ) Köperbluse/Brown shirt.
It is in “Ungeöffnet” (Unissued) condition, still unfolded and in the same shape as it was when it was made and stocked at the time. The arms and all other parts were pinned together to keep it perfectly folded according to regulations. The pins to keep it like this are still present.
There is on the inside of the collar a paper tag and on the inside of the back a brown oilcloth RZM HJ.-Köperbluse label. Hersteller 189.
On top on the inside of the collar stamped with 34-33.
Very rare to find like this and in absolute dreamcondition.
