This amazing piece of Barrowmaze [AL] fan art by Von Allen for Greg Gillespie’s megadungon captures exactly the mood and feeling of the megadungeon. It also includes the infamous “Oh, shit! RUN!” definition of OSR that Greg mentions within the text itself, and which is very, very apt.
Von publishes the ”Metal Gods”comic book, which won the 2014 Corel Endowment for the Arts Award from the Ottawa Arts Council via comiXology. He also has a two-volume all-ages graphic novel series called “Stargazer” and “the road to god knows”.
