The Bungie Store hopped into their (Microsoft paid for) time machine and traveled to the 1970's to learn about disco, big hair, and the artistic design. Then, they jumped back into their time machine, made a rest stop in 1992 for some Crystal Pepsi, and arrived back in 2007 to offer up a new 70's inspired tshirt. The tshirt is none other the Valhalla Tee with what the description calls Barracuda Fastback stripes and enough retro style to make you one cool cat. It is $16.95, but how can you put a pricetag on something that is so studly and took so much time travel research to create?
