Illustrator and designer Niall McCormack shared these covers with me. He runs a blog dedicated to Irish book covers from the 1920s to the 70s (go there), and somehow we started emailing about Harry Clarke and his influence in Ireland, which led to this post.
Niall writes that, "The books were all published by either Oifig An tSoltáthair or Oifig Díolta Foillseacháin Rialtais which were both Irish government agencies" and directs us to this exhibit for more background about publishing in Irish during this period. (You can also see more covers there.)
The designers he was able to identify all studied at the Dublin Metropolitan School of Art: Austin Molloy, George Altendorf, Olive Cunningham, Michael A Keane, and Victor Penny. Niall again:
Austin Molloy attended the college along with Harry Clarke and the two visited the Aran Islands together in 1909 while still students.
Harry Clarke taught illustration and layout at the college from 1918–23 and when he retired from the position Austin Molloy took on the role.
The other designers all attended the college during the twenties under either Clarke, Molloy, or both.
I would love to someday explore the archives of the school, now named the National College of Art and Design. Anyway, the covers:
