I chose a science book Frogs, which informs and educates the reader about frogs. I targeted teenagers who love nature and are willing to go to science museums. Instead of setting type on the same hang line, I choose to imitate the jumping of frogs, take type jump through spreads. I also drew a lot of illustrations to go with the frog images to add interest. Based on an existing typeface, I create a typography systemwith hand-drawn titles to be consistent.
