You’ve probably seen some of the line art portraits of logicians we’ve commissioned. They were done by Calgary illustrator and graphic designer Matthew Leadbeater. We’re pleased to release them all now under a Creative Commons BY-NC license: anyone is free to use them in their own work, to create derivative works from them, and to share them, provided (a) credit to Matt Leadbeater is properly given and (see license terms!) (b) they are not used for any commercial purposes.
They each come in two versions, one with a line below, and one with the portrait in a circle.
Commissioning these illustrations was made possible by a grant from the Alberta OER initiative. We gratefully acknowledge the support.
