These links to various photos attempt to recreate the style of the GSR's station signs.  The only example left in situ by the 1990s 
(I think) was Sligo (McDiarmada) Station where this photo was taken on 05/03/91:
1820 Sligo to Dublin (187+147) - Click to zoom in

They were replaced with modern plastic signs a few years later
