If you've seen Treme then you know this is a Mardi Gras Indian. I LOVE these guys. So pretty. So dedicated. So energetic. Wiki on Mardi Gras Indians. Also, Treme should be starting up again soon and they have a whole storyline involving these guys.
Gnomie goes nuts at Mardi Gras. He loves following the Indians around and getting the best throws from off the floats.
