This rare Brazilian proof issue was released in 1943 to mark the Centenary of the World’s First Postage Stamp (1840–1940). Bearing the bold denomination “60 Centavos”, the design echoes Brazil’s earliest “Bull’s Eye” issues, a nod to its rich philatelic heritage. Struck in black on ungummed paper, this proof was produced in limited numbers and never postally used, making it highly desirable among specialists. Its crisp engraving and historical significance highlight Brazil’s role in commemorating global philatelic milestones. A true showpiece for collectors of classic worldwide issues.
