"¿Who did it?" is an illustrated book with an educational twist. It's in publishing process by Piedra Santa Editorial (Guatemala, 2014).
This book was an interesting experience, having to deal not only with the usual suspects of illustrated book creation (storyboarding, editorial design input, time constraints, blah, blah, blah) but also with having to create the story with an specific educational objective, because this is, in fact, a math book for 6 year-olds :D. Take a look at some of the pages.
