At least in the world of artist Sally Davies.
Perched upon a bed with his mouth agape, a startled man focuses on what seems to be a welcoming committee of alien ambassadors in Davies’ photographic diorama Bryant Gumbel Show. Did these well-dressed foreigners arrive through the open veranda from the twilight sky beyond, or just let themselves in through the front door?
Sally Davies produced several alien-themed photographic dioramas back in 2000. You can see more of this collection over at Art in Context.
