Platinum blonde Mary Hartline (b. 1926) was a featured performer on the popular children's television, SUPER CIRCUS, during the show's run from 1949-1955. The former model's tresses and abbreviated dresses were one of the reasons the show had a substantially high male viewership.

During her years on the Chicago-based SUPER CIRCUS, Hartline, marketed over three dozen different Mary Hartline products, including dolls, costumes and boots. In addition, she was featured prominently in and on the cover of hundreds of publications through the United States.

Here she is with fellow SUPER CIRCUS cast members Claude Kirschner, Nicky (Nicky Francis), Cliffy (Clifford Soubier) in a commercial for one of the show's sponsors, Kellogg's Sugar Smacks. The crunchy, sweetened cereal also featured Mary Hartline on its box.
