50 Cruzeiros Thesouro Nacional, 1st print, 'Valor Legal'

Brazil's Tesouro Nacional notes of this period occupy an odd administrative position — technically Treasury obligations rather than Banco do Brasil or Banco Central instruments, issued at a time when Brazil's currency authority was still fragmented across multiple competing institutions. The "Valor Legal" overprint distinguishes this printing from earlier issues where the denomination carried different legal-tender status under Brazilian monetary law.

ABNC's New York plant handled much of Brazil's high-security printing through the mid-twentieth century, a relationship that stretched back decades and survived repeated political upheaval in Brasília.
