Here are three pages from the April 1961 issue of Gene Portuesi's "Cyclo-Pedia". Rochet was one of only three bike brands he advertised that year. The first page gives a bit of info on the Rochet brand, and the next two give details of the top two models advertised. Top of the line for Rochet that year was the "Ruban Bleu" (Blue Ribbon), with the "Champion de France" being the next geared model in the lineup. He also advertised a Pista, as well as some touring models and step-thrus. Rochet must have changed the model lineup for your model year. I'd never heard of the brand before seeing this cycling catalog.
