Most Exhibitions that I have come across have a 'no return' policy.
I wonder what happens to all the Mail Art at the end of an Exhibition?
Something must happen to it.
Does it get thrown away?
Does the 'curator' get to,keep it?
What happens to it?
The curator gets to keep it.
Most people don't throw it away.
Some people do throw it away eventually - and some even sell it, though that is usually not something that is appreciated by most mail artists.
Some mail art is recycled and sent out to other mail artists with or without additions/changes/transformations.
As with all other aspects of mail art, there are many answers to every question. ;)
La mayoría de las veces se queda en propiedad de la institución que la hace, ya sea ayuntamiento cultura o galerías, así es mi caso .
