The door

Write to the museum

One address reaches whoever is curating. There is no ticketing system behind it and no automated reply.

What to write about

III
Suggest a reversal
Send the link to where the creator posted it. If it belongs in a wing it gets embedded from that posting, credited and linked — never copied.
II
Ask about the museum
What is built, what is not, and when the duel might run. The questions page answers most of it already.
I
Ask for something to come down
If a work here is yours and you would rather it were not, say so and it comes down. You do not have to make a case for it. Nothing is hung today, so nothing of yours is here yet.

Before you write

Most of what people ask is already answered, including the five things this museum has not built.
