An Post has unveiled two new national stamps celebrating Irish Traveller history and culture.
The stamps feature a traditional Traveller wagon, and the 'ponger' - a tin mug.
Martin Collins, Co-Director of Pavee Point Traveller & Roma Centre, said this was a good news story and a "symbolic and historic day for our people".
Speaking on RTÉ's Morning Ireland, he said it was about valuing Traveller culture, identity, language and traditions and "making travellers visible".
He said this conveys a really powerful message that Irish Travellers have been an integral part of Ireland and Irish history going back generations.
"It's around inclusion, visibility and representation," he said.
Mr Collins said Irish history is incomplete and inaccurate in terms of what has been recorded, documented and presented, as marginalised groups like Travellers have been largely excluded.
He said that in the best case scenario, Travellers were merely a footnote in Irish history - if not completely invisible.
There is a new momentum around furthering inclusion and visibility of Travellers in cultural institutions, he added.
The stamps were unveiled at the GPO and come ahead of Traveller Pride Week, which takes place from 18 May to 29 May.
