In honor of the upcoming Skull Appreciation Day AND the beginning of year 5 of the Skull-A-Day project we thought it would be nice to make a new commemorative T-shirt so you can better express your own skull love. We're almost ready to start making them, but we need your help. Would you rather have a gray shirt or a black shirt? Take a look at the mock-ups below and place your vote in the comments. At the end of the week we'll tally up the responses on the blog and Facebook and let you know what we're going to do! Thanks.
