I think it was the other way around. I have photos of what is believed to be a 1972 event (possibly the Adelaide Hot Rod show in Dec) with the Devan in its original guise with a nameplate calling it the Devan and nominating it as a Styling Exercise, and later in 1973 painted white with a Chicken decal. There is Super8 footage of the (I think it is ) 1973 Motor Show in Sydney with the Devan as a Chicken van but I don't think it is called the Devan anymore. There are pictures also of what I think is teh Melbourne 1973 Motor Show in Feb/Mar 1973 where the White Chicken van on display is a different van. I always thught that the Devan was away being re-sprayed at this time and why it showed up again later in 1973 in Sydney.

I just found my notes from talking to Leo. The Chicken and Splash decals were around in 1968-9 prior to him coming to GMH. I'm not sure, or not sure he was sure if they were concept drawings or actual decals. I guess the former.
