Unusual to see the Iron cross worn in 2 locations (neck and breast) unless of course maybe awarded twice.

There are apparently several different versions of Iron Cross Geo. They are called The Knight's Cross of the Iron Cross.

Knight's Cross with Oak Leaves (mit Eichenlaub)
Knight's Cross with Oak Leaves and Swords (mit Eichenlaub und Schwertern)
Knight's Cross with Oak Leaves, Swords, and Diamonds (mit Eichenlaub, Schwertern und Brillanten)
Knight's Cross with Golden Oak Leaves, Swords, and Diamonds (mit Goldenem Eichenlaub, Schwertern und Brillanten)
