1. The Upside-Downs by Gustave Verbeek.
The Upside-down World of Gustave Verbeek; Sunday Press Books, 2009.

In his early newspaper strip The Upside-Downs Gustave Verbeek was mostly interested with what could be done with the configuration of the comic form. After reaching the sixth panel of the strip the reader continues the story by turning the page upside-down. Verbeek was able to employ his ambigrammatic technique by creating the characters so that when they were overturned one would become the other. Even though he was of European descent, Verbeek spent a good deal of his life in Japan, where he was likely influenced by joge-e woodblock prints, which are distorted drawings of faces that are still recognizable, but as a different likeness, when rotated 180 degrees.
