The Adventures of Sherlock Holmes
Two fonts are used for the title cards. The upper one is MGB Patrician, which also goes under the names Mazama, Aegina, Opti Protea, or Verve. The lower one is called Rubens, alternatively known as Ravenscroft or Mansion.
Conan Doyle’s Holmes was keenly interested in typefaces and font identification. It was, for him, a professional forensic tool that provided facts for his theorising:
“The detection of types is one of the most elementary branches of knowledge to the special expert in crime, though I confess that once when I was very young I confused the Leeds Mercury with the Western Morning News. But a Times leader is entirely distinctive, and these words could have been taken from nothing else
