The lad in the picture is Ian Paisley. He was a prominent unionist back in the day. (Unionist being someone in favour of maintaining the six counties in Northern Ireland being part of the UK)
From the wiki page:
Ulster Says No was the name and slogan of a unionist mass protest campaign against the provisions of the 1985 Anglo-Irish Agreement which gave the government of the Republic of Ireland an advisory role in the governance of Northern Ireland.

As I recall (and I was young at the time so this may be wrong) it got rolled out for various other stuff.
Catchy slogan in fairness.
Oh that’s a great spot. Didn’t notice it initially.
