Designed by Ressa McCrae, this shirt is called "What Fools These Mortals Be." She's been featured on their site before. I think it looks pretty cool. Anybody can slap a public domain image on a t-shirt. This is not that. This is a unique item, designed specifically for old Will's birthday. He's going something of an eye-roll going, wonder what he's thinking?
(*) Note that this is not an affiliate thing and I'm not making money off the deal, I'm posting entirely because it's a "Shakespeare's-Birthday-only" thing and I highly support merchants and other folks recognizing our holiday ;)
