Yes, this t-shirt is actually signed by Will Ferrell himself!  Bid on this fun, rare t-shirt from the great Will Ferrell Broadway show "You're Welcome America, A Final Night with George W. Bush."

This large 100% cotton grey T-shirt says "He's awesome. He's tenacious. He's...tenawesome!" on the back and will always remind you of Will as Dubya. Ferrell, who famously depicted Bush on Saturday Night Live, also wrote the play, capping off the Bush years in this final satirical homage to the President.
