Comic artists come in many different varieties: stylists, technicians, craftsmen, visual revolutionaries. Some draw on real life, some experiment and push off into spectacular flights of fantasy. There are those who hone and improve on existing approaches, and those who look for something new and different.
The amazing thing about Milton Caniff is that he was all of the above, and a whole lot more. He was the best-known and most popular cartoonist of his day. His narrative and artistic innovations expanded the comic vocabulary, and reinvented the form of the adventure strip. And his influence was felt both by his contemporaries in the comic field, and by the generations that followed.
