First off this chap - Dino by name used to be a mascot for a milkshake drink called "Yazoo", and also managed to star in some brief, short but memorable adverts some yoinks back. I often think about this guy from time to time. Such a shame they're really hard to come by, even on YouTube :P
Now this was fun - on the left is some fanart of Chuck Jones' earliest design for the Road Runner, which eventually became the familiar design (to the right) to this day =)
Finally, this one's for the UK fans - Sad Sack from "The Raggy Dolls"...which seriously needs a DVD release this time next century....!
