UPDATE: The first picture shows a group of identically built yellow 1969 Camaro RS/SS convertibles heading to Le Cirquit Mont-Tremblant in St. Jovite, Quebec, Canada to perform the driver parade laps prior to the start of the Labatt's 50 SCCA Can-Am event held on June 15, 1969. Member Bbrsss wrote the following on February 9, 2025 in my thread about this event: "There were 12 or more 1969 Camaro RS SS yellow convertibles that GM of Canada used as promotion to parade drivers for 1969 Can-Am series. They were all identical with 396-325 hp, auto, standard white interior, remote mirror, deluxe belts, endura, cowl hood, chambered exhaust and all of them were shipped to Canada on May 7, 1969."
