France Miginot Line ON NE PASSE PAS One Does Not Pass

Round medallion, 36mm across, thin brass metal. Words on top banner, ON NE PASSE PAS, (One Does Not Pass) with a Large Artillery Gun in a Bunker. Piece of Purple ribbon attached to back. Small hole in base, I would imagine for suspending something. Interesting pin likely issued by France to promote the MAGINOT LINE prior to WW2.
