This impactful 1990 Soviet stamp features a white bird, possibly a gull, rising from a polluted Earth, with black oil-like stains trailing from its body. The Russian text "ЧЕЛОВЕК, ПОЩАДИ!" translates to "Man, Have Mercy!", urging humanity to protect the planet. The dramatic imagery reflects environmental concerns—particularly oil pollution and ecological destruction. Issued by the USSR Post (ПОЧТА СССР), it has a face value of 15 kopecks. A powerful piece highlighting Soviet environmental awareness during the late 20th century.
