That little box shows up quite often over the next few comics. By the time I finished all of these I really started to wish I had made it into a stamp. But it opens up later, and that would have meant another stamp.
I’m looking at making up some Stamp of Adventure shirts in the near future. My only real concern is how the stamps will survive the transfer to a silk screen. (The first few will be hand done by me, not via something like CafePress.) We’ll see how that comes out in a test run.
