This striking 50 Franc stamp from Congo honors Laika, the first dog in space, launched aboard Sputnik 2 on November 3, 1957. The design shows Laika seated in her capsule with the powerful rocket rising against a vivid cosmic background. Issued during the 1960s, it reflects global fascination with the Space Race and the heroic role of animals in early space exploration. A highly collectible issue, it appeals to both thematic collectors of space and science and those drawn to Cold War-era philately. A must-have historical tribute piece from Congo’s rich commemorative series.
