[02/08 update: check the comments here; unfortunately, a number of people over an extended period of time have complained about problems or delays completing their orders from Reckon. Lead time on orders not-in-stock have stated leadtimes of up to 3 months. Just so you know.]

Only by special request, of course. Otherwise you get Jon Stewart on a Onesie-shaped American Apparel infant bodysuit, or on a kid- or adult-sized t-shirt. It's a new, limited-run design from Chris, the poet-genius behind Reckon Wordwide.
