Quoted from xyntec:

Walking Death was a big disappointment to me, never even heard of it before the pin came out, don't like it either and wouldn't want it in my living room, Game of Thrones doesn't ring a bell either, suppose it's a game...
Maybe series and games are big in the USA, don't think so here in Europe, I think a general theme (like Mustang) or a Music Theme would sell a lot better here...
