Jimmy Riddle

I have a vintage hand puppet (can't say how old but has heavy sign of wear patina) it has a smiling man's face with a little hat (like a clowns pork pie hat) perched on one side of his head. It is not sad or cheeky like you would expect of a clown but more like a characterization of a person. It has it's own original box with the name Jimmy Riddle written on it. Was Jimmy Riddle an old comedian? or personality? Anyone know??

I looked on Ebay and found Jimmy Riddle items -- "African adventure" books and what looks to be a blues 45. Continuing the search...
