besides, what's the very first thing you read (at a glance)? "king of hawaii" blares off the page. then you read "squirt". andybody who knew about those bands and cared enough to follow them would see that in an instant and then continue on the read the details. they'd probably react to the headline with a smirk and a giggle. and they would see that maybe third, or even later.
that's an excellent point, and one discussed at length constantly on this site. where DO you draw the line between dispersing information and being a private art statement?
in this case, it was only a hundred copies or so posted around the tavern neighborhood and the rest distributed at the show. so, this one served the thin borderline between the two.
besides, rock posters in seattle got so wild and unreadable for so long, that any scrap of paper on a telephone pole that looked peculiar would be an instant magnet to rock geeks. the very illegibility became a hook. and it also served to scare away the "mainstream" people that the bands didn't really want to show up and spoil the gig.
so, this is a very peculiar and subtle form of marketing (or 'branding' if you like) that became prevalent in underground circles over the last few decades.
actually, the people at the seattle center (not my contact, but my client's boss) represent the city of seattle and really freaked out at the word 'shit'. but jeff gilbert (my client who was organizing the thing for the city) really went to bat, saying, "but it's a rock concert series!" so we changed it to the asterisk and everybody shut up.
the budget got slashed, however, and the full color extravaganza ended up being a black on green paper flyer.
