Preserved postal items bearing a special surcharge are usually rare. Most often, this is because the surcharge was in effect for only a short period, and also because people tended to postpone sending any non-essential mail until the surcharge period ended.
Stationery from the Sarajevo provisional issue, additionally franked with a 0.5 din stamp, in accordance with the 1.50 din domestic postal rate that came into effect on 15 January 1946, sent on 5 February 1946 from Drinovci to Koprivnica. The postcard bears a mandatory “Children’s Week” surcharge label, required on all mail during the week from 3 to 10 February 1946. A scarce item.
