For those who are wondering, this is an art installation called “Armoured Pram for Derry” by Eamonn O’Doherty, and appears to be from a 2016 “Making History” exhibition at Ulster Museum.
From what I can gather, it was created in 1991 but restored in 2012 after O’Doherty’s death.
This was a particularly bad case of some bagel being cut in half.
