WWI British RFC Royal Flying Corps Officer's Collar Badge on Old Card -- Vimy

Description

With so many fakes and reproductions, it's nice to encounter a legitimate and authentic RFC badge. This one is mounted to an old card which reads, "Great War - Royal Flying Corps Badge Souvenir of Vimy." Likely, this is the Battle of Vimy Ridge fought April 9th to 12th, 1917.
Clearly there is damage to the badge on the left laurel leaves where there is a distinct break. No idea what caused such a violent break here as well as a bend in the badge overall, but it was significant for someone to pick it up, keep it, and mount it to the card.
Lugs and pin present on reverse.
Nice piece that displays well.
Always happy to combine shipping on multiple wins!
