In the early 60s, the Kuklapolitans starred in these TV spots on pesticide safety. They are the earliest surviving color films of the troupe that I've found. (Though KFO pioneered color television in the 50s, only black-and-white films of those shows exist.) The numbers on the boxes - 4R and 5R - could mean that there are 3 other spots out there. Click on the box covers to watch them with RealPlayer.
