Kodachrome slides taken by cultural anthropologist Robert Creswell.
Creswell conducted a major study of the inhabitants of Kinvara, Co Galway in the mid-1950s,
He discovered they enjoyed bacon..
Cresswell died in 2010 and donated his archive of black and white photographs, colour slides, 16mm film footage, documents and notes etc. to the nation. He also insisted the hoard remain copyright free. Bit of a dude to be fair.
