An Post has issued a new set of four stamps celebrating eight Irish men who played a significant role in the epic Antarctic expeditions of the 1800s and early 1900s.

Irish men were at the heart of the pioneering expeditions to Antarctica. Co Kildare-born Ernest Shackleton and Tom Crean, from Annascaul in Co Kerry, are two of the better known explorers, and have achieved worldwide recognition for their bravery and perseverance.

The other six men featured on the stamps, five from Cork, are less well known but no less important in the contributions they made to Antarctic exploration.

They include Edward Bransfield (from Ballincurra); Patrick Keohane (Courtmacsherry); Robert Forde (Bandon), brothers Mortimer and Tim McCarthy (Kinsale) and Francis Crozier (Banbridge, Co Down).

Leading Irish illustrator David Rooney explained how he wanted the stamps to shine a light on the impact Irish men had on Antarctic exploration.

“Like most people I was aware of the Shackleton and Crean expeditions, it was fascinating to delve into the adventures of a figure like Francis Crozier, who set out in 1839 as commander of HMS Terror on the Ross expedition,” he said.

“Crozier, his ship and all of his crew were subsequently lost, along with Sir John Franklin, on their ill-fated search for the North West Passage in the Arctic just a few years later.”

The four stamps, two for national postage and two for international, and a First Day Cover envelope are available at selected post offices and anpost.com/shop.

Dublin Port has highlighted An Post’s issuing of a €1 stamp to honour the Dublin Dockers’ Society and their strike during the War of Independence.

The stamp, of a set of two designed by Ger Garland, reproduces a headline in the Freeman’s Journal on 21 May 1920 — ‘Dockers Down Tools’ — and refers to the Munitions Strike whereby dockers refused to discharge British munitions from a vessel in Dublin.

The strike action — which continued until December 1920 — quickly spread across Ireland, with rail-workers also refusing to handle munitions.

Issued on 24 September, the new ’N’ rate stamps covering postage in Ireland and accompanying First Day Cover envelope are available from main Post Offices, Dublin’s GPO and online at www.anpost.com/shop

#IrishLights - An Post has today (Thursday 6 October) a set of stamps to commemorate the Commissioners of Irish Lights.
