I am working on the editorial design of an article dealing with U.S. military history. In the article I am using a graphical interpretation of an original U.S. Army insignia. The insignia is of the Ghost Army Unit of the U.S. Army during WWII. The graphic is used instead of an image of the actual insignia due the style guidelines of the entire publication the article will be a part of. However, the graphic still needs a label underneath/next to it.
My question is: How should I label it? I cannot put a label saying "Insignia of the Ghost Army Unit during WWII" because that is not true since it is a graphic modelled after the original insignia. Should I label it "Replica of the insignia of the Ghost Army Unit during WWII"? Or "Representation of the insignia of the Ghost Army Unit during WWII"?
Does anyone have some useful suggestions?
Here is an image of the original insignia as well as of the graphic used in the article:
