This product is a vintage WWII military trench art brass airplane pin or brooch, likely originating from the United States during the World War II period. The item falls under the category of collectibles, specifically in the militaria theme, showcasing original period items from the era. This unique piece would be a valuable addition to any collection due to its historical significance and originality, representing a piece of American military artistry from a pivotal time in history.
The pin or brooch does have some patina wear as shown in my pictures. It has no markings. The pin measures about an inch in length by an inch tall.
