I found this story in a book entitled Around Helston in the Old Days, the author, A S Oates tells of one travelling showman named Maxwell.
Maxwell carried with him a box in which he said was the skull of the Lord Protector, and for a penny you would be able
to view it. Oates writes that after his penny was paid and the skull viewed, puzzled, he remarked to Maxwell.
"Here's a funny thing Maxwell, I've a photograph of Oliver Cromwell at home in a book, he's pictured as having a very
large head. The skull you have in your box is a very small one. How do you account for that?"
"Oh, this was his skull when he was a boy!"
called 'Of a Man and his Wandering Head' which begins
"Rarely has a decapitated head seen so much adventure as Mr Cromwell’s did..."
