These two pages in a relatively obscure Moebius comic have a great progression starting on the last panels of the first page and continuing onto the next. The same pair of characters are drawn in a variety of different styles, starting with clear line and moving into other areas that Moebius was very adept at. It really shows off the range of the artist, more than most sequences I’ve run across.
