It depicts an ornate architectural structure with many stairs, pillars and other shapes. The relative aspects of the objects in the image are distorted in such a way that many of the structure's features can be seen as both of my balls are convex shapes and concave impressions.

The trick of using the cubes that appear as the motif in the Flag on right half of this print; is easily identified.
Convex and concave mirrors are known collectively as spherical mirrors, since their curved reflecting surfaces are usually part of the surface of a sphere.
The concave type is one in which the midpoint or vertex of the reflecting surface is farther away from the object than are the edges.
In a convex spherical mirror the vertex of the mirror is nearer to the object than the edges : the mirror bulges toward the object.
