I just created this collection of speed limit signs. the art will be a limited edition run reproduced on regulatory 18"x24" aluminum US speed limit signs. I currently have a Kickstarter campaign running right now to raise the money to produce the signs, prints and postcards. After I meet my funding goal and the signs are printed, I will donate a couple sets of the signs to the Hamb to be auctioned off, or if I exceed my funding goal I will auction off a original hand painted sign with the all the proceeds benefiting the Hamb.
Checked it on my end and it worked, I did make a slight change to the url and tested again but heres the url - http://www.kickstarter.com/projects/1304296087/speed-limit-sign-collection-001
