This is a perspective-corrected version of @druadic's hi-res backbox version below. I've gotten things rolling by reconstructing the damaged / lost corners & nearby areas, altho better blending and correcting the shadowed edges would also be nice. The lossless PNG version is available for anyone who wants it.
