After liberation, the communist authorities strictly prohibited occupation symbols, including the Ustasha flag and coat of arms. Therefore, it is very unusual to see a 1942 commemorative stationery with a large Ustasha coat of arms used after the liberation.
Commemorative stationery for the 1942 exhibition of aircraft models sent from Zagreb (22.V.45) to Negotin, Serbia, by military post and censored by the military censor. Unusual use of stationery with Ustasha symbols under the communist regime.
