I’ve got this shirt, too! I bought it at P&P ‘98 May in Charleston, SC WIC tour. I refuse to put it or any concert t-shirt in the dryer. I’ve worn this one to the crossroads in Clarksdale, Mississippi while visiting lots of blues landmarks including performing at the Sunflower blues concert, a visit to Tutwiler, Indianola (performed at BB King’s blues museum) and many blues legends grave sites (Charlie Patton, etc), and just across state lines to more blues related historic sites in Helena, Arkansas, etc.
