The insignia you receive will either be the one pictured or one in similar condition. This is from a United States Army Air Forces collection which we will be listing more of over the next few months. REV90 LFJX6/10

7+ (Very Fine+): The insignia shows little wear except for a few spots on edge.

As with all my artifacts, this piece is guaranteed to be original, as described.
