$3.75 for a guitar? Made with life-like Reel-Ton cardboard, perhaps? No: real wood, perfect for those occasions “when people gather for festivals and fun making.” Check the copy for the Black Knight:

“Penthouse parties - Hollywood high jinks - in vaudeville and broadcasting studios - everywhere you go, black guitars are the rage!” Yes, people across the land listening to radios wondered: is that a black guitar I’m hearing?

Remember, Supertone was the name for the instruments. Silvertone was the name for the batteries.
