Calvin and Hobbes is one of my fav books after Mafalda. Although both have many similarities Mafalda's more political and humanitarian approach makes her a powerhouse of human rights, while calvin depicts his insatisfaction with art and an ongoing existential questioning. Bill Watterson's creation, reminds you of the contrast of innocence and the twist of evil kids sometimes have. Hobbes is the best friend anyone (including adults) can have. Functioning not only as his imaginary friend, but as his voice of conscience. This comic strip reminds me so much of how important it's to have fun and preserve the innocence that once we had as kids.
