looks Citroen, well actually IS. C the double chevron on frnt - isnt that the Citroen (french co) symbol? Never saw one either, amazing. Leave it to the French, no?
This same exact pic seen in da google space: https://www.google.com/search?client=safari&rls=en&q=1960+Citrone+van&ie=UTF-8&oe=UTF-8 research (its all right there) will tell if custom (B sides paint) or oem. I think it is the "HY van" ? and Tissler is aftr mrkt like the coach builders (wrk directly w/the big 3 in this country to = ambulances, hears, etc).
don't know, could B photo-shopped. Several in same exact position, background - just different color/logo on side... "HY" is the corrigated 'ugly' one (Tissier - not sure that reference).. "MrWhitt" came up as I went a lill deeper (a photographer). Just not sure & will get onto other things right now. It is interesting, tho, thnx
Apparently the Citroën Tissier van never really existed. It was just a photo shop deal from a guy named Moller. He also did one in white, and also a Panhard van.
