Hip Hop family tree

I was at the library the day before a few weeks ago. What had happened was.... I came across this "comic book" that was all about the foundations of hip hop in the early 80's, and from what I can see each volume progresses threw the eras of Hip-Hop... It's cool to look at, but what i really loved was the MC's on the front and back cover. Look at it above.... I see everyone from the Beastie Boys to MF Doom, Rakim, Hammer, Fuckin' Humpty Hump... Lol... check out Kris Kross in the bottom left... This shit is crazy.
