Brazil 1843 30r Black, Slanting Numerals

Brazil · 1843 · 30r

This stamp, known as the 'Bull's Eye' or 'Olho de Boi', is the first postage stamp issued by Brazil and the second in the world, following Great Britain's Penny Black. The design features a large numeral '30' in an oval frame with intricate engine-turned patterns, a security measure to prevent forgery. It was printed in black on yellowish paper.

Issued under Emperor Dom Pedro II, the Bull's Eyes were part of a major postal reform in Brazil, demonstrating the nation's modernity and efficiency in the mid-19th century.
