1979 Swiss Gspécial Break brochure

This Swiss 1979 GS brochure has only four pages. The brochure list the Gspécial Break, with 1.3 liter engine. This is curious since this car is only sold for a while. Later it was replaced by the GS Spécial Break. I have never seen another copy of this brochure, so I gather it is quite rare. I myself bought it in aprox 1988 at a fair. Price indication 10 Euro.
