Sign-holders aren't specifically unique to Dublin, but they are an intrinsic part of the city.
A new documentary by Ste Rogers, funnily enough called Signs Of The TImes, focuses on the 'human directionals' - that's the advertising industry term for them - of Dublin.
More pointedly, however, the documentary focuses on the stories and events of their lives, why they're in Dublin and what they're about. It's a fascinating little watch.
Check out the documentary in full below.
