Sherlock Holmes in his deerstalker cap
Basil Rathbone wears a deerstalker cap while playing consulting detective Sherlock Holmes in the 1939 film The Adventures of Sherlock Holmes. The deerstalker cap, while closely associated with Sherlock Holmes, was not part of his equipment in the original stories. As a 2012 story on Smithsonian.com noted:
"Sherlock’s unmistakeable deerstalker hat... was never mentioned in the printed words of the Holmes books. When Sidney Paget illustrated Doyle’s story, The Boscombe Valley Mystery, for publication in The Strand Magazine in 1891, he gave Sherlock a deerstalker hat and an Inverness cape, and the look was forevermore a must for distinguished detectives."
