This commemorative 0.50 dinar stamp from Jugoslavija (Yugoslavia) was issued in 1970 to mark the 100th anniversary of the telegraph in Montenegro (1870–1970). The design, in a striking minimalist and geometric modernist style, features a stylized telegraph key in white and gold, surrounded by radiating red and black lines symbolizing the transmission of communication signals.

At the top, the Cyrillic inscription reads “Сто година телеграфа у Црној Гори” (“One Hundred Years of Telegraph in Montenegro”). This issue reflects Yugoslavia’s emphasis during the 1960s–70s on celebrating technological and infrastructural progress through elegant, abstract designs.
