1941 Prisoner Correspondence from Gusen Concentration Camp

The single sheet or prisoner stationary is double sided with writing on one side. Approximately 5-3/4 inches by 8-1/4 inches. The stationary was printed for use at the notorious Mauthausen concentration camp in Austria, but was modifed by hand to reflect that it was being sent from Gusen, a sub-camp of Mauthausen. The document shows age toning and edge nicks but overall it is in very good condition.
