Very nice!

In similar cases I have used the Perspective Tool in "Corrective
(Backward) mode to square up warped photos-of-photos and documents,
sometimes followed by running Filters > Distorts > Lens Distortion
against all or part of the image.

The Distortion Correction Between Paths plugin adds another useful
tool to the "bent document correction" arsenal; my initial
experiments seem to indicate it will be especially effective with
photos of pages in books and similar geometries.
