Sean Avery has a handful of tattoo designs which we know of, including the traditional Irish symbol known as the "Claddagh ring" located on his right shoulder.
On his left shoulder is a Celtic cross along with several rose tattoos.
His most recent tattoo is located on his left forearm and reads "You used to be alright, what happened?", which is the lyrics from "15 Step" by Radiohead.
