Jourdan Pereira studied Graphic Design at Universidad del Pacifico in Chile and Computer Typesetting and Design at the Fashion Institute of Technology in New York, and worked mainly as a comic-book artist for twenty years, the first ten of which he spent illustrating licensed properties such as Teenage Mutant Ninja Turtles, G.I. Joe, Transformers: Animated, Astro Boy, Digger & Friends, Ghostbusters, and Disney/Pixar characters for American publishers like IDW Publishing, Mirage Studios, and Boom Studios; before crossing the Atlantic to Scotland’s DC Thomson where he tackled Ivy the Terrible, Lego City, and Pie Face comics for the weekly The Beano, Snooty & Scamp (Lord & Lauser) at Wendy, countless illustrations for WWE Kids Magazine, and was finally chosen as a Peter Davidson fill-in artist on The Sunday Post Fun Section comic-strips (which include Oor Wullie, The Broons, and Wee Harry). He also delved into vintage comic-book restoration and re-coloring, starting out with The Purple Smurfs (Papercutz), online Last Kiss cartoon panels, DC Comics’ Justice League International Omnibus, and collections dedicated to Uruguayan cartoonists Carlos María Federici (Detective Intergaláctico ), Geoffrey “Fola” Foladori (El hombre que fue una biblioteca), and Emilio Cortinas (Hazañas de un viajero del tiempo), all published by Uruguayan comics convention Montevideo Comics. Between 2014 and 2016, he dedicated himself to woodcut printmaking, taking part in Japan’s MI Lab Residency program, designed to teach “mokuhanga” (Japanese water-based woodblock printmaking technique) to foreign artists. Four of his biblical woodcut prints were also included in the book Revealed: A Storybook Bible for Grown-ups, alongside works by Albrecht Dürer, Rembrandt van Rijn, Franz Marc, and Eric Gill among many others. Commercially, he applied his printmaking expertise to the development of adult coloring books, mainly for Dover Publications in the USA. From 2017 onward Jourdan Pereira chose to pursue a career as a nonfiction author, focusing mainly on activity and puzzle books, like his Bible Power Puzzles volume, debuting as an English language writer with the publication of his Astonishing Bathroom Reader in 2020, and its 2021 Bizarre Bathroom Reader sequel. In September, 2021, two Spanish language titles translated by Jourdan, Sonic: El destino del Dr. Eggman, and Locke & Key: Bienvenidos a Lovecraft, were released by IDW Publishing. The end of 2021 will see his return to adult coloring books with the publication of his Masterpixels book series.
