Here are a few contenders for the newly formed Cartoon Network Alumni group on LinkedIn. Oh Cartoon Network, how you've evolved!
Obviously all trademarks belong to Cartoon Network (this is not officially endorsed by the network), and the fine people in their legal department would want you to know this: CARTOON NETWORK, the logo, and all related characters and elements TM & © 2010 Cartoon Network.
If the PPG version is chosen, perhaps I may do some more interpretations of the logos of their classic shows.
I'll let you know how it goes!
