Bosnia Miltärpost Ablage Gorica on postal money order for 813 Kronen postmarked Vitina (also a rare cancel) with 2 copies 40 heller 1917 and 20 heller 1917. The 40 heller is quite rare on cover.
These cancels were from often tiny sub post offices in Bosnia. They were never to be used to cancel stamps, so on single stamps you hardly ever see them, only on postal forms, postal cards and on covers. Ablage cancels are all very rare. About 200 different Ablages existed and as far as I know no (more or less) complete collections ever existed.
Shipping and handling $3 and $0.50 for each item that can be sent together.
Shipments with a value of over $100 will be sent by registered mail, which costs $10 extra once.
