GameStop giving out poster as Pokemon X/Y pre-order bonus?

Nintendo hasn’t announced any pre-order bonuses for Pokemon X/Y, but GameStop may be giving out its own special item. There is at least one report of the retailer handing out a poster, measuring in at over two feet wide.

So now the question is: are all (or many, at least) GameStop locations handing out the bonus? Or was this just a special occurrence?
