Rabbitholepromotions has an Instagram acct, showing off the work that Rabbit Hole does. THey're an ad agency that does street murals as advertising. Yep, like the AIDES and Red Cross ad murals except you know, for real. Murals are interesting, they have vastly different looks around the world northern Irish murals used to be mainly supporting a political point of view, remembering the fallen, and that sort of thing. Nice to be far enough away from that to suddenly have murals used as colorful splashes of ad-space instead.
Dublin mural / street art ads - an ad agency dedicated to just that.
