(2B pencil on A6 card) A parody of the type of advert you'd see in the old comic books. What nasty little child wouldn't want something as wonderful as this?
Flying Robot in the Sky, watercolor. I used my new Holbein paints. (I love them.) Drawn with a Pilot Falcon SEF using Platinum Carbon Black. A trifecta of Japanese paint, pen, and ink.
(2B pencil on a 87mm x 139mm postcard) The idea of owning an exotic pet was always used in comic book adverts. The most well known one being the sea monkeys. People thought they were getting something really special, until it was pointed out to them that they were just brine shrimp. But imagine if something like a pet demon was available!
