I have never seen one even some of the ones that look like pictures are usually paintings. But in a book called Emma and Joseph: Their Divine Mission written by their great-great granddaughter Gracia N. Jones there is a painting of him in his military attire this picture he actually posed for so it is pretty accurate of how he looked.
If there is any real pit cures of him the RLDS(I dint remember what they changed their name too) owns them. Emma gave all of those things like that to her children who gave it to their (the RLDS) church.
