A lot of people considered him to the best that ever was during the height of graffiti fame. You can see him in the pics that @NewLife posted up. The first pic is from his "Children of the Grave" I think that was the second one. There's a great scene on the second bonus disc of WildStyle when one of the guys said it was incredible that DONDI did a whole car/top to bottom without having to step back and gauge his spacing.
Even his simple tags were dope
If you really want to get into it, there's a great book that was done on him, here's the link from Amazon:
