Nobody's ever been able to find a contemporary example.
I think everybody just KNEW.
Well actually I saw a photo of one of those signs in a history book about the Irish in America. It was a advert for some kind of job and the last line said No Irish Need Apply.
‘That “No Irish Need Apply” sign never existed.’
It was “No Micks Need Apply” and “No Micks On the Grass.”
The signs never existed, because you say so?
