The bicycle model offerings of the four undated early 1970s French brochures on this website were compared with one another, with the dated 1969 and 1975 French brochures, and with the 1972 and 1974 Cycles Peugeot Bicyclette Catalogue Pieces Detachees Et Accessoires.  Based on the comparisons, these brochures are believed to be of 1971 or 1972 vintage.  This dating is supported by the Les Peugeot Cyclos catalog shown with the first brochure which was acquired at a 1972 autoshow.  It has the same layout and people as the Les Peugeot Velos brochure.
