Issued in 1985, this Soviet Union stamp features the renowned painting Portrait of Olivares by Spanish master Diego Velázquez, preserved in the State Hermitage Museum collection. The issue highlights the USSR’s long-running series celebrating masterpieces of world art housed in Soviet museums. The warm brown tonal printing carefully reproduces the classical Baroque portrait style, making it an appealing item for both art-thematic and museum-thematic collectors. With clear typography and a strong historical art reference, this stamp remains a desirable collectible from the late Soviet cultural series.
