Escher, first printed in March 1955.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 convex shapes and concave impressions.This is a very good example of Escher's mastery in creating illusion of \"Impossible Architectures\"." ] ,
