Well, it's really not a store. It's actually a Cafe Press shop. Paradoxically, although Pipepages is made up almost entirely of advertising and marketing material, it is a non-commercial site (this despite its dot.com domain). No ads, no banners, nothing for sale, really.
Anyhow, a while back I scanned a really cool Yello-bole catalog cover. It was so cool, that I thought it would make an excellent T-shirt. Fortunately for Yello-bole fans everywhere, I was given the greenlight by Bill Feuerbach of S.M. Frank. The thing is, I don't have time to make and sell T's. So, I set up a Cafe Press shop. I've tried to mark-up the items just enough to cover the monthly fees. I hope that they are within reach of anyone who might be interested.
From time to time, I get inquiries about the site logo. This is a nice way to address those as well.
I have no idea on the quality of this stuff. If anyone actually buys something, would you let me know if it's any good?
