I saw the previous Wine t-shirt, with the drunken penguin, but it wasn't really me and I don't think there are anymore anyways. For those of you who didn't know about it, I don't think it was advertised very well (maybe we should have had a products tab or links in World Wine News more regularly).
I started playing with zazzle.com and ideas for a Wine shirt for myself. Here's what I have so far in case anyone cares or would like one too: http://www.zazzle.com/tuxg2_wine_t_shirt-235593182956669764
I plan on giving half of any profits to Wine through their donation page & use the rest to set up some Wine embroidery items (I'm thinking a hat & zip-up sweatshirt). After that I'll update the amount that goes to Wine.
I thought it was a nice approach because it's print on demand and it's possible for people to customize with their own slogans instead of having to vote on one.
