Mules being led from Santi Quaranta (now in Southern Albania) to Ioannina (Jannina) on the shore of Lake Ioannina. Both towns were in Ottoman Turkish hands in 1906, Ionannina (opposite the Island of Corfu) being re-absorbed into Greece following the Balkan Wars (1913). Interestingly (or just to add some more confusion) this card was sent from one of the Austrian post offices in Turkey!!
