Portugal King Carlos I Postage Due Stamps

Portugal · 1904 · 5 réis, 10 réis, 20 réis

This set includes three definitive stamps from the reign of King Carlos I. Two are postage due stamps (J16 and J23) featuring large numerals indicating the amount to be paid by the recipient, and one is a newspaper stamp (P1) with the King's portrait. The postage due stamps are typographed in a simple, functional design, while the newspaper stamp features a more traditional engraved portrait.

Issued in 1904 during the latter part of King Carlos I's reign, these stamps reflect the standard postal needs of Portugal before the 1910 revolution that established the First Portuguese Republic.
