Marshall’s Auburn Shirt in Last Cigarette

Did anyone else notice Marshall’s awesome vintage Auburn Tigers shirt in Last Cigarette Ever? I’d love to find someone in the HIMYM wardrobe department. I love Auburn…and that shirt. Take a look below:

First of all, War Eagle. Secondly… Any ideas where I might find said shirt? I love looking for HIMYM music, but I need a shirt source.
Cheers.
