In January 1944, a small group of German officers occupying the island of Brač, Croatia, decided to commission the printing of local postage, ostensibly to benefit the local populace, but in actuality to make a profit for themselves.
A local print shop was ordered to produce the stamps, but was only equipped to overprint existing stamps. It was therefore decided to overprint stamps of the former Yugoslavia.
Quantities printed were 400 of MiNr. I, II, and IV, and 500 of MiNr. III, V, and VI.
50 sets were left in Dubrovnik, and eventually came into the possession of local philatelist Erwin Zwerger. All known copies probably came from this batch. The remainder were transported to Brač, where a few were postally issued. It is believed that all of those taken to Brač were destroyed during the battle for the island in June 1944.
