Unknown stencil artist in Dublin (or is it Banksy ???)

When I was in Dublin (Ireland), I came accross these stencils in a shop. For the ones who know Dublin: it was a shop with Jeans and streetwear in the St. Stephen's Green Shopping Center, on the second floor if I remember well. The stencils were on the wall next to the stairs leading to the next floor within the shop. I entered and asked the shop assistant who didn't have a clue who had put these stencils there and also didn't pay them too much attention. I think they are really good. Unfortunately, a part of the last stencil (the guy who is fishing) was a bit covered by a poster.The style looks a bit like Banksy but there was no indication that he left them there.... Any ideas ???
