"Saw the Lady"
Artist Jamie Isenstein is closely involved in her artwork:
"Since Duchamp, sculpture can be anything, so if you put a living body into the sculpture, is it still sculpture, or is it a performance?"
Sometimes, though, she has to take a break.
That's when she puts up a little sign that says "Will Return".

In the above, the smoke is from a humidifier, and so we may classify "Smoking Pipe" as a piece of sculpture.
Pipes have a tradition in the art of the surreal, as shown in this painting by René Magritte.
"The treachery of images - This is not a pipe"
Since his painting is only the image of a pipe, he had to write "This is not a pipe" on his painting. If he had written "This is a pipe", he'd have been lying.
