This 1 ruble Soviet postage stamp, issued in 1956, celebrates the Belorussia (Белоруссия), a passenger vessel of the Baltic Shipping Company that operated the international route between Leningrad (now Saint Petersburg) and London. The design depicts the sleek liner cruising under clear skies, with Cyrillic inscriptions highlighting the route “ЛЕНИНГРАД – ЛОНДОН.” The stamp belongs to the “Soviet Merchant Fleet” series, which showcased the USSR’s maritime expansion and international travel connections during the post-war era. It is a classic example of Soviet nautical philately combining art, technology, and propaganda.
