It's hard to imagine that composite sketch being to helpful, but stranger things have happened.
It's possible too that a scared young girl, pressured to provide a description of a mean man she'd rather forget, might revert to a mental image of a bad guy or cartoon character from an old TV show or movie. I'd think Howdy Doodie would be a bit before her time, but Mad Magazine's Aflred E. Neuman might not be, nor Actor Michael J. Pollard- who's been in some scary roles.
Or, perhaps, some more prominent, recalled from a picture seen at school, perhaps.
