Brazil Bull's Eye Stamp

Brazil · 1843 · 30 réis

This stamp, known as the 'Olho de Boi' or 'Bull's Eye', is the first stamp issued by Brazil and the second in the world, following Great Britain's Penny Black. The design features a large numeral '30' within an ornate oval frame, without the country's name or a monarch's portrait, a common feature of early stamps.

Issued under Emperor Dom Pedro II, the Bull's Eye series was part of a major postal reform in Brazil, demonstrating the nation's early adoption of this innovative system for pre-paying postage.
