Éire is dressed in a red robe with decorative interlace design at the top; she holds a spear in her hand and ribbons that connect her to ships dotted around the coast of Ireland. West Britain, is dressed in the Union Jack and crouches on the east coast of Ireland looking towards England with outstretched palm."
