I found File:Mapcc07.png and File:Mapcc08.png. Same uploader, same graphic style, one file is labelled 'I created this work entirely by myself.' but the other has "Author Daniel Kaufmann, Aart Kray and Massimo Mastruzzi. Permission granted." There is no indication of OTRS, but they are scholars who have co-authored several papers on related topic. If the pictures are simply badly sourced to some table or such (maybe this?), it's probably ok (except the badly sourced part limits their usefulness), but they could also be a copyvio. Can someone look into this? --Hanyangprofessor2 (talk) 07:21, 27 November 2017 (UTC)[reply]
Backwards copy, the book was published in January 2011 according to Google Books but the text has been in the article since 2009 at least. The book is also self-published, if that makes a difference. Hut 8.522:13, 19 December 2017 (UTC)[reply]
