Authentic USAF Office of Special Investigations (AFOSI) wall emblem, originally displayed in a command building. This large-format emblem is an official piece of Air Force unit decor featuring the full-color OSI crest: a globe, wings, sword, and lamp of knowledge symbolizing the USAF’s intelligence, investigative reach, and global security mission. This sign is not a reproduction – it was removed directly from an active-duty AFOSI office. It is made of lightweight hardboard or laminated PVC material with a semi-gloss finish. Unit: USAF Office of Special Investigations (AFOSI). Dimensions: 28.5″ tall x 28″ wide. Material: Lightweight hardboard or foam-backed PVC. Condition: Good vintage condition with some edge wear and surface scratches (see photos). Use: Formerly mounted on a USAF command wall. A rare historical piece ideal for veterans, collectors of U. Air Force memorabilia, or military wall display. Hard to find and highly collectible.
