Artist Chad Wicks points out,  "There may be some slight issues referencing the death mask because it looks as though, from his skull and other accounts, that after he fell out of the window from being shot, he was struck in the face. This could have broken his jaw or disfigured him in other ways. However, no accounts from those who knew him suggest it looks nothing like him, so as far as what exactly Joseph looked like, the death mask is the best thing we have."

Including many realistic details such as Joseph's eyes, hair, scar and even stubble, Wicks explains:  "My profession is centered on User Experience and User Interface design,"
