Seems like a sensible approach. I gave a pretty big pair of plastic bags of tech T-shirts (some/many never worn) to charity over the holidays. I still have far more than I will ever wear (much less need). I guess one could imagine someone wanting to make a museum display of old tech T-shirts at some point but the reality is that physical storage is expensive.
You can frame t-shirts, and turn into wall art:<p><a href="http://sometimes-homemade.com/how-to-frame-t-shirts/" rel="nofollow">http://sometimes-homemade.com/how-to-frame-t-shirts/</a><p>I could imagine Google or Facebook or some other company with plenty of money doing this on a spare wall at a new HQ. It's geek heritage.
