This full mint never hinged sheet of 240 stamps from Ireland’s 1968 definitive issue features the iconic stylised Irish dog, designed in the Celtic Revival tradition. The design is a modernist interpretation of animal motifs inspired by early medieval manuscripts such as the Book of Kells, reflecting the country’s rich cultural heritage and the revival of national identity through visual art. Printed in vivid orange by typography on gummed paper, each stamp bears the inscription “Éire” and the denomination ½p, and was intended for standard domestic printed matter postage. The stamps are perforated 15 x 15 and were issued in sheets of 240 divided into two panes of 120, separated by a central gutter, with control markings visible in the selvage. This issue marks a shift towards bold graphic elements in Irish philately, coinciding with a period of cultural modernisation and state promotion of Celtic design as a national symbol. The reverse of the sheet is fully gummed, with no signs of handling or previous mounting. It is listed as Scott IE 250 and remains a highly recognisable and frequently collected example from Ireland’s modern postal history. Condition Mint never hinged full sheet with original gum, sharp perforations and full selvage; minor fold along gutter typical of storage but no separation or damage. Estimate "$80 – 100".
