This Holiday Special cover looks pretty good!
I wanted to attempt something similar myself, as my first contribution to the forums, but you beat me to it. Guess I'll have to think of something else.
Does anybody knows if the official ad for the holiday special ever appeared in magazines such as Rolling Stone? Because in that case, maybe a higher quality version of this ad could be found in a compilation like this:
