This mug is patterned after The Strange Case of Dr Jekyll and Mr Hyde -- an 1886 Gothic novella by Scottish author Robert Louis Stevenson. It follows Gabriel John Utterson, a London-based legal practitioner who investigates a series of strange occurrences between his old friend Dr. Henry Jekyll and a murderous criminal named Edward Hyde. Turns out that the good doctor has invented a transforming serum that allows him to become the debased and monstrous Hyde for periods of time.

This mug shows both personas (Jekyll and Hyde) split down the middle and holding a beaker of the serum. He/they wears a blue coat and top hat.
