Holiday on Wheels by G. Boulanger

I picked up this Print from a thrift store, because it was such a fun color piece. It was in a cheap Plexy Glass poster type Frame.
When I got it home I took it out of the stratched frame and realized it was larger & had been folded to fit into the frame.
I also noticed that in the righter lower It says Touchstone Publishers 1976, Imprenten France. Unfortunately, not in the best condition. The main picture is pristine, there are just tears and folds areound the edges.
I looked up the artist, but can not find alot regarding the Imprinted France. Does anyone have any information regarding this particular print?
ANY HELP would be appreciated-thank you
