Summary

Media data and Non-free use rationale
Description	Sketch by M. C. Escher of a Moorish mosaic tessellation in the Alhambra, 1936. The sketch appears to be inverted with respect to the Alhambra tiling; Escher has marked a circled X at the top of the sketch, while its neighbour has a circled X at the bottom, so he may have turned the page for convenience while drawing.
Author or copyright owner	M. C. Escher
Source (WP:NFCC#4)	Original publication: The World of M. C. Escher Immediate source: as above
Date of publication	1974
Use in article (WP:NFCC#7)	M. C. Escher
Purpose of use in article (WP:NFCC#8)	It illustrates the painstaking attention Escher started to give to tessellations from the Alhambra in 1936.
Not replaceable with free media because (WP:NFCC#1)	None exists; all of Escher's drawings are in copyright.
Minimal use (WP:NFCC#3)	The image is the only scan of an Escher tessellation study in the article and indeed on Wikipedia. It is used at poor resolution.
Respect for commercial opportunities (WP:NFCC#2)	The image has been published at much better resolution in the named source for 40 years, where it forms only 1/4 of an image. The drawing is itself a technical detail alongside many of Escher's far more appealing artworks.
