Just as a lark, I started to play around with designing the letters of the alphabet as Muppet characters. Turns out that a few of them translated quite well, so I thought I would put it all together as The Muppet Alphabet. I hope you enjoy this as much as I enjoyed putting it together. It has also inspired few other Muppetational ideas that I may post in the future.
By the way, I know I cheated a little with Sam the Eagle as "E." The only other idea I could come up with was the Elvises, but I thought Sam deserved the spotlight. Plus, I couldn't come up with any ideas for X, not even after considering Fraggles and Sesame Street Muppets.
UPDATE: I've posted a NEW and IMPROVED Muppet Alphabet at http://muppet-mania.blogspot.com/2011/06/ladies-and-gentlemen-its-muppet.html. I think this may have solved the issue with the missing "X"
UPDATE: Along with the NEW Muppet Alphabet, I've also started taking on a whole bunch of new projects. Designs based on The Simpsons, Sesame Street, Pixar, the Muppets and more can be found at http://baboondesign.blogspot.com/.
