I've also been researching an East Coast Canoe and Kayak Festival and Ballet posters.
One art event that I really like is the Renegade Craft Fair. It travels around the country yearly including places like Chicago, San Francisco, and London.
Info on website:
At the Renegade Craft Fair you can expect to find only the best indie-craft and DIY artisans! Featuring both local and national talent, shoppers can anticipate a vast arrayof independently designed jewelry, clothing, paper goods, home + garden goods, posters, artwork, plush objects, bath + body products, and so much more!!
