The art is not what costs the money — the staff is.
The museum’s collection should *rented* to other museums, with a small core of “adopt-an-exhibit” finalists (in other words, everything normally on display would be available to be bid on, but with a minimum figure) remaining in an appropriate amount of space — probably elsewhere.
I like the building, and the area had been spruced up between the first time I remember visiting (in my teens) and the most recent times (about 15 years ago), perhaps the structure could be repurposed, iow, sold to a developer.
Good idea Civ...
