Very interesting internal document from the Litzmannstadt ghetto. Order 70 wrapped armbands from the post office by Judenrat Litzmannstadt, department "Wasche und Kleider Abteilung" Laundry and clothes department!
The order is in Polish, here is its translation:

"We have a gentlemen's order from 28/12 from last year for 70 armbands. We do not have any stock in relation to the goods. Please send us the goods and we will execute the order. The armband pattern sent to us is returned together with this letter."

A very unique document, interesting ghetto stamps. Good condition
