www.gigposters.com. Gigposters is by far my favorite website of them all. For inspiration and for fun. For incredible typography and some of the best visual communication out there.
I'm a music fanatic and I think I first found Gigposters.com by doing a Google search on some band. Then I bought a poster I really liked and the rest is history!
Most of the funny stuff I see on the internet comes from Gigposters and believe it or not, on more than one occasion, I have read breaking news on Gigposters before reading it on my Yahoo homepage! You could probably make a case that I spend too much time on the site, and you might be right, but I can never repay Gigposters.com, site creator Clay Hayes and the artists who post their work for how much I have learned and been inspired. So thanks!
