His postcards are all that remains. They can be seen in the Clonmel Museum who got Hugh Ryan's collection.
Robert A. "Sonny" Cash was one of the most prolific postcard producers in South Tipperary.
Sonny, partially crippled in his youth, grew up hump-backed. He took to photography as a teenager and from his father's shop on Main Street, Carrick-on-Suir, he travelled the surrounding countryside in a side-car building up a large collection of photographs, some of which he reproduced as postcards.
He died in a fire at his home above the studio in Carrick and all his glass negatives were destroyed.
The postcards are all that remain of this important historical record. The earliest Cash postcard on display was postmarked 1904, taken when Sonny was only 15.
