This 21-cent commemorative stamp from the Bahamas, issued in 1976, honors the 100th anniversary of the first telephone conversation (1876–1976). It features a detailed portrait of Alexander Graham Bell, the inventor of the telephone, against a soft gradient background symbolizing communication and progress. Issued during a period of rapid global telecommunication expansion, this stamp celebrates a century of human connection through innovation. It remains a fine example of mid-20th-century Caribbean design celebrating global scientific milestones.
