An Post has issued three stamps commemorating the centenary of the 1913 Dublin Lockout.

Produced by Irish designer Ger Garland, the stamps feature photographs from the "Darkest Dublin" collection of three prominent figures associated with the Lockout, with significant scenes in the background.

One stamp shows James Connolly with the ITGWU building in the background.

Constance Markievicz is pictured against a photograph of children outside tenement buildings in Chancery Lane, which is now Bride Street.

Jim Larkin is shown against a photograph of the Bloody Sunday Riot in Sackville Street, which is now O'Connell Street.

The new stamps and a booklet containing extra background information are available at, the GPO in Dublin or at main post offices.

Centenary commemorations will take place in Dublin on 31 August.
