This Iraqi stamp features a portrait of King Faisal I, the first King of Iraq, who reigned from 1921 to 1933. The design shows him in formal attire, framed with Arabic inscriptions and the denomination “5 Fils.” Issued in the early 1920s, this example bears the bold “ON STATE SERVICE” overprint, indicating official government use. Such overprinted stamps were circulated for administrative correspondence and are scarcer than their regular postal counterparts. Collectors value these both for their historical association with the formation of modern Iraq and for the distinctiveness of the overprint.
