Coheed and Cambria Heart shirt from the early 00s. Totally awesome, classic design. This one specifically was available through Merchnow. It's a size Youth Medium (10-12) printed on an FOTL Heavy Cotton blank. 2002 is a guess on the year, same year as The Second Stage Turbine Blade's release, since I'm not sure when this specific one was printed (just that it's one of their early designs).
