Not sure some of you would like this but an alternative could a mural of the man, designed by the Res Dubs lads.
Would be very cheap and could hire an expert, even if it meant getting them down from Belfast.
The problem would be location but it could go up in June, down in October if required.
Google street cam could be used to scout locations around Croker.
It some cases its allowed by Dublin city council.
Just a thought.
