 * This image shows the bottom part of the mouse, which gives a clearer idea of its construction and working and which can't be seen in the one you linked to. It's also held by the hand of its creator which may give it some historic value - while showing its scale and expected grappling position at the same time.
 * This image shouldn't be deleted without discussion. It certainly is not a candidate for speedy deletion under criterion F1, which is for lower quality versions of the same image. This is not the same image than the one you suggested. Diego (talk) 16:25, 25 February 2012 (UTC)
 * I've nominated this file for speedy deletion. – Finnusertop (talk ⋅ contribs) 18:54, 15 March 2016 (UTC)
 * can you provide a reason why you nominated this image for speedy deletion, dismissing the provided fair use rationale? Diego (talk) 22:10, 15 March 2016 (UTC)
 * We have free images of the mouse at c:Category:Douglas Engelbart's prototype mouse. If the purpose is to illustrate some specific aspect of this mouse (e.g. the way it's hold, as the rationale states, or indicating scale), it's possible to be done by drawing a free diagram. At any rate, in order to justify the inclusion of a non-free image for that purpose, the behavior of holding the mouse should be discussed in detail with sources in the article to meet WP:NFC (WP:NFC). Currently, only the image caption states that the inventor is holding the mouse in the picture (why or how this is significant is not discussed). Note that this is the only picture in the article showing a mouse being held (free alternatives exist for showing how mouses in general are held, but for some reason this article does not incorporate them). The discussion above implies that this is a "historic" picture, which while may be true is not enough to satisfy NFCC#8, see WP:NFCI§8. How the bottom part of this mouse works is not discussed vis-a-vis the image in the article, either, so it does not need to be shown. In sum, this image combines many useful features, but none of them are employed so as to meet the non-free content criteria, whose purpose is not to allow us to replace inferior free images with superior non-fee ones, but to use non-free images when they are irreplaceable and necessary. – Finnusertop (talk ⋅ contribs) 22:34, 15 March 2016 (UTC)
 * The scale might be conveyed with a diagram, but illustrating the mechanism with it would be woefully inadequate- we don't have schematics of the mouse design that would provide more information than what is shown in the image, so any portrayal in the schema would be either losing information or inventing details (thus original research). And the mechanism of that particular device *is* discussed in the article with RSs in the same paragraph that the image accompanies, so contextual significance per NFCC#8 is met.

 * You're right, it's discussed. I've withdrawn the nomination. – Finnusertop (talk ⋅ contribs) 22:58, 15 March 2016 (UTC)
