Interesting piece of history this an anti Clann Na Poblachta ad from Fianna Fail from the 1948 General Election Campaign.
The Fianna Fail candidates were Sean MacEntee (later Tainiste) and Michael Yeats (son of WB Yeats) and MacEntee was elected. Amongst the Clann Na Poblachta candidates was Noel Browne (who was also elected).
