Classic Mopar Literature

Hello to all on line on this cold weather day in NW Illinois (and other points around the country)--Curious about the distribution of some brochures advertising the 1971 Rapid Transit System vehicles. I believe some may have been distributed via popular magazine publications as inserts but others were dealer offerings only. Can anyone shed light on one of the RTS brochures showing a 9 block cover photo that includes a funny car, Petty's # 43 stock car and other full color / psychedelic pages inside? This may have only been a dealer handout....
