Baseball cap worn by Tom Selleck in the role of Thomas Sullivan Magnum on the television series Magnum P.I. The dark blue cap features a patch with "VMO2/DA NANG" stitched in gold thread surrounding a gold eagle insignia on a dark blue field. The insignia refers to Marine Observation Squadron 2 (VMO-2), an observation squadron of the United States Marine Corps which saw extensive action during the Vietnam War.
The crime drama series Magnum P.I. aired on CBS from 1980-1988, and followed the titular private investigator's detective work on the Hawaiian island of Oahu. Magnum was a veteran of the United States Navy who served as a Navy SEAL and intelligence officer during the Vietnam War, and the series was lauded for its depiction of Vietnam veterans' successful post-war careers and lives. Selleck won the 1984 Emmy Award for Outstanding Lead Actor in a Drama Series for his portrayal of Magnum, and the show was a popular success, regularly ranking in the top twenty programs on television in the United States during its run.
