In 1977, Friends Industries made a Sesame Street Color-Your-Own Play Stage kit. The kit includes four black-and-white coloring panels representing the Sesame Street set, which can be colored many times with crayons; the panels wipe off with a sponge. The set includes six Muppet characters -- Big Bird, Ernie, Bert, Cookie Monster, Oscar the Grouch and the Count -- and the set panels also have Luis, Little Bird, Herry Monster, Lefty the Salesman, Betty Lou and Super Grover's cape.
