"...lately he's been overheard in Mayfair..."
You all know the song, don't you? "Werewolves of London" by the late Warren Zevon. I used to sing along when it came on the radio: "He's the hairy handed gent who ran amuck in Kent, lately he's been overheard in Mayfair.You better stay away from him, he'll rip your lungs out Jim. Huh! I'd like to meet his tailor. Aaaaahooooo, werewolves of London, aaaaahoooooooo..."
My friend Nix sent me these scans from the first Bentley of Scotland Yard in Pep Comics #1, January 1940. "Monster of Mayfair" is drawn by M. Gutwirth.
Thanks, Nix. Aaaahoooooo!
