“Originally called Journey Around My Skull [and now called 50 Watts], the site started as an old-fashioned book blog, what Schofield calls an ‘I like this book and you should read it’ blog.

Soon I started to collect illustrated books and to contact artists about showcasing their work, and the blog morphed into its graphic-intensive state.'”
