I live searched Elmo pictures and found some cute one that could be used on an invitation. if you go to "free Elmo pictures" things would be even better. There are also Elmo coloring pages. You could print those plain adding party info at the bottom or something, fold and mail. The kids could then bring the pic to the party and an instant coloring activity would result.
Hee hee hee...how about an invitation from Dorothy the Goldfish to a party for Elmo and [birthday person's name]?
