Katie Shanahan first came to readers’ attentions in the Flight anthologies, but her most recent project is a collaboration with her brother Steven. Silly Kingdomis a 36-page, black-and-white, all-ages fantasy comic about a princess and prince who throw a surprise party for the 211th birthday of the kingdom’s wizard. Though the $10 price tag is hefty, there’s also a PDF version for $4 and Shanahan’s charmingly expressive art is always worth checking out. The book also includes bonus material like the making-of documentary comic excerpted above. Katie’s posted the entire making-of comic at her blog.
