Who came up with this way to the egress sign?

The "Way to the Egress" sign is famously associated with the artist and filmmaker Derek Jarman, particularly from his 1986 film "Caravaggio." In the film, the phrase serves as a metaphorical and literal exit, symbolizing both a physical escape and a deeper commentary on art and life. The sign has since been referenced in various cultural contexts, emphasizing themes of departure and revelation.
