My 2 cents, if I may digress from the name-calling.
I've never heard HOF, but from what I've seen of other posters that were deemed "appropriate" for them,
it seems fairly on target. You got your skull, a pair of ghouls, armor and pointy stuff.
As far as putting a political statement on a poster goes, my PERSONAL take on it is that it
trivializes the impact of the message.
I've done quite a few anti-Bush posters, but I wouldn't use an advertisement for a rock show to
push that agenda.
If the band likes it, that's the bottom line, and I bet they do.
