These stamps from Monaco feature the profile portrait of Prince Louis II (1870–1949), who ruled Monaco from 1922 until his death. Designed by G. Cheffer, the series was part of Monaco’s definitive issues during the interwar period.

• 50c brown, 60c green, and 80c red-orange values shown here belong to the “Prince Louis II” series, which was issued between 1924 and 1932.

• The finely engraved design emphasizes Monaco’s tradition of elegant classical portraiture.

• These definitives were widely used for everyday postal needs, making mint, well-centered examples more desirable to collectors.

• Variations in perforation, paper, and shades exist, offering additional collecting interest.
