I had an earlier re-printing of this collection (which first appeared in the 'fifties) that got damaged, so I was pleased recently to get a copy of this latest edition. It has over seventy one-a-page reproductions of Escher's best-known prints, selected by him, with his brief but very useful comments on each. The quality of the reproductions is very good, with crisp linework, solid blacks, and dense, rich tonal areas. About 15 prints are reproduced in colour. Really exceptional value at the price. As the text is so short I recommend Bruno Ernst's "The Magic Mirror of M. C. Escher", which explains in detail how the images were created, as a companion volume. Together they are really all the Escher fan needs.
