The German Cross was instituted by Adolf Hitler in 1942 as an award ranking higher than the Iron Cross First Class but below the Knight's Cross of the Iron Cross. It was issued in two levels: silver and gold (the color of the wreath around the swastika).
This award was actually a pendant than a cross, and was a rather gaudy design, helping it gain it's nickname as "Hitler's Fried Egg". It was worn on the right hand pocket of the tunic. If a recipient was awarded both the silver and gold levels, both of them could be worn on the uniform.
This award was also available in cloth form, which made for easier wear on the combat uniform. Far more awards in gold (combat) were made than in silver (support).
