>>43281745I assume the left one is the original because it looks different than the other two in a few aspects since you said two are proxies/fake the one that looks different to me seems like the obvious choice.
The Word Savannah looks grey-ish and the Plains symbol in the text is slightly worse looking. The one on the left looks a bit darker then the ones on the left (but that might be because of the flash) and the corners in the left one are different but almost not noticeable.
