Yeah, just those eight. Granted, Dr. King was something of a controversial figure in his day, and I understand why he would NOT show up in the comics of the early 1960s, but with all the time-travel and flashbacks and parallel worlds and whatnot that appear in comics, I'd have figured that should warrant at least a few more appearances since then. As a points of comparison, Oprah Winfrey has the same number of appearances and Nikola Tesla has at least double.
