A photo, published in Field Day Review 2006 as part of a piece by NL Hogan with the caption 'Free State Troops searching a building' will come up for auction in Cavan on the 19th and 20th of April.
The picture, owned by General Richard Mulcahy before being gifted to a vendor who sold it at auction in April 2010 is estimated to fetch between €400 and €800 when it goes up for auction at Victor Mee Auctions.
Mr Mee said he was "honoured" to have been given the opportunity to find a new home for, what he described as, "this rare piece of Irish history and heritage".
He also highlighted that it wasn't often he got to see such a well-preserved artefact and one that is so well-documented in the annals of Irish history.
