The era of shorts before movies was still working its way downhill, when Duncan Renaldo seized upon a few performances he'd done as the CISCO KID in the forties, and grabbing Leo Carillio as his sidekick Pancho this time, developed a series of shorts that played in theatres in the forties with --commercials-- like Good and Plenty Candy. Probably one of the most innocuous concoctions with nary a fat calorie since the Jujube.
While Bill Boyd was doing the same thing with Hopalong Cassidy to much more commercial success, his spinoffs in the fifties, merchandise etc, built a $50M dollar empire when $50M was worth, today, $500M easy--Renaldo wasn't quite the businessman. Successful nonetheless.
He was so precognicient, he had these filmed in color, anticipating color TV by a decade! So, after three or four seasons in reruns, he was able to see a revival in the series as color swept the nation in the mid to late fifties.
The other characteristic--here was a hero born in 1906--making him a western hero in his late forties and early fifties, pretty long in the tooth for a cisco KID! Leo Carillio was born in 1880, so that made him in his late sixties, forming another one of two Mexican heros in the early sixities, in his eighties. Your takeaway, kids are kids forever.
Renaldo was still trying to capitalize on the character as late as the late seventies, when he passed away. Carillio was still appearing as Pancho in parades and in public forum till his death in the early sixties.
Wonderful oaters, these still hold up today. I wouldn't mind if they preserved the old commercials, but they're gone.
