Hello James – I used a copy of this in Revolution. Its of the West Connemara Brigade Flying Column taken I think in the Spring of 1921. Im not sure if I got a copy of it from Mercier Press’s Collection or Kilmainham (Check Revolution – but I think both have copies) Basically i’d contact Kilmainham and Mercier asking for a copy. Once you can get a good quality copy (preferably scanned) then it should be easy to get blown up. FYI – I think this pic may be featured in Nollaig O Ghradha’s book “The Civil War In Connaught” and that it names all those pictured.
