If you google images of Honest Joe's there are photos of both the pawn shop building and truck with "Ruby" written on them. However, to me it appears that those pictures are from the early 1970s. Pictures allegedly taken in the early 1960s do not show the "Ruby" signage. I believe this interview is from the HSCA in the late 70s. I don't doubt her statements but I think it is possible that her memories of the "Ruby" signage might have been tainted by later sightings. Just my two cents.
