This First Day Cover (FDC), issued in 1977, commemorates Samuel Hahnemann (1755–1843), the founder of homeopathy. His groundbreaking observation that Cinchona bark could produce malaria-like symptoms in healthy individuals became the cornerstone of his medical philosophy—just as the falling apple was to Newton and the swinging lamp to Galileo.

⚠️ Note: The closing flap is slightly worn due to the natural ravages of time, but the cover remains a valuable collectible for philatelists and history enthusiasts.
