Architecture of Mexico, [s.d.]

The first image (upper left) is of an unknown piece of architecture, perhaps a beam or part of a doorframe, bearing a small carved portion at its center. The second image (upper right) is of what appears to be the corner of a window/mirror bearing a carved design.

The third image (lower left) is of a statue set in a carved opening in a wall? panel, while the last image (lower right) is of a row of carved images set against another wall.
