PD ineligible?

[編集]

Do we really need the OTRS and copyright stuff with this image? I claim this is ineligible for copyright, because it is simply a picture of the two possibilities I could draw if someone asked for "two circles, tangent to one another." Thoughts? -- Jalanpalmer (talk) 22:47, 17 March 2010 (UTC)[返信]
