Did you catch this in Locke & Key? One of the most lavish and elaborate television sets is The Key House. The show's makers built their own homes because they were unable to find one that matched all of their requirements. Although pricey, the procedure was well worth the effort. The interior design of Keyhouse contains a number of comic book-related references. Sharp-witted readers can spot an iconic logo in the comic book. The gorgeous, elaborate woodwork gave this symbol a subtle wink. You may see the comic book series insignia carved into the wood trim at The Key House's entrance.
