Original Production Art for "Scooby-Doo Where are You?"

Thanks to ScoobyAddicts board, i found some of these original piece from when they were designing Scooby-Doo, this was from when it was going to be called "Who's S-S-Scared!" but the original concept was thought to be too scary for children, by CBS. So they re-worked it, into what is now know as Scooby-Doo!

Here are the pictures
