Julian's flags, the ones of which I am already familiar, were rendered quite excellently and accurately.
Of course I would never use as true the image of an undocumented T-shirt flag. I was merely laying it out as the only image of the 5th/13th Arkansas that I've ever seen. Were it a bald-faced imaginary creation, the creator would probably not have had the insight to include "Belmont," the only one of this series that would have had this honor, but without documentation it is still just a curiosity.
As I said, I do hope this flag surfaces someday.
