Envelope and Stamps marking Aer Lingus's 50th Anniversary

"To celebrate Aer Lingus's 50th anniversary special commemorative stamps were issued by an Post together with a special envelope. Inside is a card outlining Aer Lingus's 50 year history. As both myself and my late husband worked in Aer Lingus at the time I got the envelope and stamps and had it posted (in order to have the stamps stamped with the special stamp) through the postal system to my husband at our then address in Rush Co Dublin.
