What’s in that crate?

We’re figuring it was probably Jeffrey Harris’s large untitled drawing from 1982 that was in the then National Art Gallery’s exhibition The heart’s key. If so it would probably make this crate one of the last to have the old National Art Gallery stencil on it before it became The Museum of New Zealand and thence to Te Papa. Very humble protection compared to the monster crating public art galleries wrap their treasures in today.

A+O tell us that for the full 10 points the answer is in fact Neil Dawson's sculpture Framework II made in 1988 giving it even better creds for being one of the last NAG crates.
