Not sure if anyone knows about this but there was an event in 2012 where Volume 26 of Kingdom was redrawn by 1000+ participants, mostly random people, and broke the Guinness World Record of a single volume of manga drawn by the most people.

Here’s the original Japanese version of Volume 26 for your comparison: http://raw.senmanga.com/Kingdom/VOLUME_26/1
Most of the panels were drawn by random people like you and me so some of the panels were quite badly drawn and some became parodies of the original(my favourite was Farmer Tou/Teng cutting wheat in the field). However, some of the panels were drawn by big names such as Inoue Takehiko(left panel in the picture), the author of Slam Dunk, and Eiichiro Oda(right panel in the picture below), the author of One Piece. The picture is kinda small but you can find the original version somewhere in the link above.

Panel drawn by Masashi Kishimoto, author of Naruto
Panels draw by Masakazu Morita(Shin’s anime voice actor), Jun Fukuyama(Sei’s anime voice actor) and Rie Kugimiya(Ten’s anime voice actor) in that order. Im sure Yoko Hikasa(Kyokai’s anime voice actor) participated too but i cant seem to find her panel online.
For more panels drawn by notable artists, do visit the first and second links below.
