Miniature Masterpieces: 100 years of Irish stamps, a joint exhibition between An Post and the National Print Museum that celebrates a century of postage stamps in Ireland, is now open at the National Print Museum. Dedicated to the history, design and production of these miniature masterpieces and Irish cultural ambassadors, the exhibition displays not only a wide selection of Irish stamps but also original artwork, design proofs, printing plates and other treasures from the An Post Museum & Archive, some of which will be on public display for the first time.
