Dumb. Urban Outfitters saw Neil Diamond’s opening day jacket, and decided to jack it. Neil Diamond wore the jacket because 50 years later, he’s still heartbroken that his favorite team left for LA. Urban Outfitters printed the shirt, because they are trying to sell shirts to their target market of people in their 60’s? Dumb.
No Mas already printed this design a few years ago. The Urban Outfitters shirt, the No Mas shirt and the Diamond jacket are all reproductions of an old design from 1957, so everyone, including Neil Diamond, is jacking it from whatever fans made it fifty years ago.
(EDIT: This IS just the No Mas shirt, available from the Urban Outfitters site. Most likely, Neil Diamond got his jacket from the same source.)
