Also try ebay. Frequently, posters are listed there by private collectors.
The Jazz and Heritage Festival has closed their online store, so other Jazzfest souvenirs are no longer available online. The information below is pretty old (it even pre-dates the online store), but I've left it in case you're desparate and want to give them a try. But ebay remains your best bet.
The Festival T-shirt vendor is a local company called Southern Silk Screen.

You can get the new flags from the Jazzfest store. The old flags were sold at http://www.folkart.com/~latitude/flags/jazz.htm, but they were sold out, last I checked. I've heard that if you want to order several, they'll consider reprinting them. Contact them for details.
