This is what a 25-year-old Boing Boing T-shirt looks like
by Mark Frauenfelder from on (#2196S)
I drew this bOING bOING T-shirt design in 1991, when I was living in Boulder, Colorado. I gave one of the shirts to Evan Ravitz, a wonderfully talented tightrope walker, juggler, activist, and founder of the Voting By Phone Foundation in 1989 (if his idea would have been adopted and people could vote over the internet via their phone or gaming console, Hillary would have won).
Anyway, Evan has managed to hang onto his T-shirt for 25 years, and it looks better than new! He posted this photo of it to Facebook.
If you want to do some long-term planning and have a T-shirt in 2041 that looks this good, you can get started by buying a new one here.
