Calvin & Hobbes first strip

Today a new comic strip hit the American Newspapers: Calvin & Hobbes by Bill Watterson. I didn't discovered Calvin until years later in El Pequeño Pais pages a dominical by Spanish newspaper El Pais. It's one of the comics I liked from these days and still today is one of my favourites. It ran for a decade until December 31, 1995. The strip preseted above is the first one, as appeared with Bill Watterson's comments taken from the Calvin and Hobbes 10th anniversary book published in 1995.
