U.S./Canadian Comics

It should come as no surprise that a whole lot of comics are American. Also included here are Canadian comics, as they are for the most part pretty similar to their southern counterparts due to the large amount of intermingling between the two cultures, businesses and talents, and often see distribution in both regions regardless of origin.
