PS from "VOJNA POSTA*Br.92*19.5.17" fr. with 10c. canc. with "OUVERT par lAUTORITE MILITAIRE*309" and posted from "VOJNA POSTA*Br.999*21.5.17" with Serbian censorship "PREGLEDALA/VOJNA CENZURA (57)" in blue (No.57, period of used May 1917). The post mark "VOJNA POSTA*Br.92*19.6.18" was apparently applied with wrong date and then crossed out as erroneous.
