Bulgarian Airlines Wooden Cigarette Box -"Balkan"

A rare find, a wooden cigarette box from Bulgarian Airlines, with the word "Balkan" printed beneath the logo on top. The box is decorated with light blue, yellow, green & red shapes on the top and sides. The box is also etched with circles and lines on the top, a square pattern on the back and ovals on the front and sides. The box has room for 20 cigarettes in the lid and place for I would say 40 in the main section of the box. A slot for a cigarette on the far right of the box is missing. The box is 7 3/4" by 4 1/4' by 1 3/4" tall.
