Hello there!
There is no creative brief attached.

Is it there now?

Yup! :)

Kodak, Blockbuster, Toys R Us, JC Penny, GE, McDonalds

Are you sure it would be ok to use these names without written permission?? I'd be a bit concerned about registered trademarks. I will use them, and would love a shot at this cover, but I did want to ask.
Thanks for posting this challenge. Should be fun.

PS How do I get all the files with graphical elements so things can be edited changed etc.

do you want to try one or two more title/font treatments or leave for now? I feel I need to give you more precise feedback and direction.
