Ireland 2d Coil Stamp, Pale Green, Watermark Sideways

Ireland · 1935 · 2d

This definitive stamp features a map of Ireland, including Northern Ireland, within an ornate Celtic-style border. It was printed in a pale green color and issued in coil format for use in vending machines. The error variety is distinguished by its watermark being oriented sideways, a result of the paper being fed incorrectly during the printing process.

Issued by the Irish Free State, this stamp was part of a definitive series intended for everyday postal use. The sideways watermark error makes it one of the most significant rarities in Irish philately.
