Clearly inspired by Banksy, this stencil just showed up near the Sta Apolónia station in Lisboa.
Apparently, this is a “station entry” that would be an asset to the people who live in that neighborhood, as opposed to go around the whole station just to get in if you have the ticket.
Funny thing is that if this actually was a Banksy piece, the wall would be taken down. Can you see the joke in that? Eheh
Thanks to Nuno Leitão for the heads up and photos.
