The painting by Caitríona Lucas, who died during a rescue operation off Kilkee in September 2016, has been adapted into a tribute to both her and the crew of the coastguard helicopter Rescue 116 who were lost in March 2017.
Two stamps show separately a rendering of the Sikorsky S-92 helicopter, and an Irish Coast Guard rescue boat similar to what Caitríona had crewed.
The commemorative stamps were launched at the GPO last week by members of the coastguard and Caitríona’s widower Bernard.
In a joint statement, coastguard units in Skerries, Dun Laighaire and Greystones said their thoughts are with the families of Caitríona, Capt Dara Fitzpatrick, Capt Mark Duffy, winch operator Paul Ormsby and winchman Ciaran Smith.
“This gesture by An Post is heartwarming to us all,” they added.
