You are not the only one, I'm sure. We have a lot of these itmes,
partially bought by the museum/the city in the postware time for charity
reasons, some came into the museum by pure ignorance, especially in this
mass.
You can't destroy them!! Find other ways.
We give every year a bundle of those subjects to x-mas charity auctions,
if good enough, we use it for representive gifts by the mayor. But this a
very dangerous thing. Politicans very easy understand the museumas a
self-service for gifts, a bit of Idi-Amin...
Be very careful in deaccessioning those items, think about the opinion of
still living (and probably better) artist who might give parts of your
work to you.
Be very careful, but you can perhaps rent a garage and store all this
stuff there for the next twenty years. Be sure it is rain- and antproof,
look once every year inside an decide again.
You can also decorate the town-hall with it.
