This is asssumed to be from 1973, the same year as Luis Ocana’s Tour de France victory because it shows a picture of him in an earlier Tour and none of the decals on the bikes illustrated are the later type as fitted to Ocana’s bike. This would indicate that there was not a lot of preparation time between Ocana’s win and the publishing of this brochure:
“The Brand of the Tour de France Winner 1973”
