Good job, look forward to seeing futher digital shots. The RCA "Mark Series" color sets were first introduced in late 1957 as the CTC-7 models, a new chassis design. This was the follow up to the CTC-5 models. The Mark 10 series (CTC-10 chassis) as advertised in your great RCA/Disney dealer promotion ad was around 1961. This was when Disney's "Wonderful World of Color" program moved from ABC (Then called "Disneyland")to NBC and was then telecast in color. RCA was a primary sponsor and Disney's large library of color cartoons & features was perfect to sell color tv's. Although it worked both ways as Disney used the hour to promote its theme park and new feature releases in brilliant "Living Color."
