Hot Trumpet

This Patent was issued in 1981 in New York. if you look closely it is a trumpet with a gas cartridge and a spark mechanism that can be triggered by the soloist at the highlight of his solo so a burst of flames spit out of the bell.
This gives me visions of a big band. Four fully equipped trumpets and a trombone section without any hair left. You just have to visualize that, I’ll wait… you see? Good!
