Use in article (WP:NFCC#7) | Discriminant Book |
Purpose of use in article (WP:NFCC#8) | For visual identification of the object of the article. The article as a whole is dedicated specifically to a discussion of this work. |
Not replaceable with free media because (WP:NFCC#1) |
Can't be replaced as the booklet, i.e photograph is intrinsically tied to the Naval Enigma during World War II, as part of the enciphering process. |
Minimal use (WP:NFCC#3) | This is a unique historical document, of sufficient size to make the Gothic font readable to the average Wikipedia user. It is a military document from the Second World War and will be used in a single article, described above. The image will be thumb-nailed during normal use. The colour is important as it is used by U-boat staff to indicate that it is a disposable document, e.g. after attack. |
Respect for commercial opportunities (WP:NFCC#2) |
I have been unable to locate any uses of this image, outside cryptography sites, and as such I believe commercial opportunities are limited. |
Other information | This is a critical image with a unique historical perspective. No other image can replace it, as it represents the process of enciphering a message using the Naval Enigma. |
