Is this late in their work, early, middle?

No, no, no.

No, this is, this is more on the early side.

And in fact, there's a quote, I think it's from Peter, uh, Smithson, who says, "For us personally, the pause in, uh, building lasted from 1954 to 1962." You know, so after Hunstant- Hunstanton School, um, which is '49 to '54.

Uh, so they're sort of saying at that point they're stopping and...

But they're, they're not, because they're, they're building things.

Upper Lawn, um, Solar Pavilion is '59 to '62.

It's pretty diffuse, I think.
