Open since the late 1800's, the St Joseph's Blind Boys School of Drumcondra had a program to teach the boys trades, one of which was how to make rosaries. This helped them earn extra money, as they usually lived at the school. This is a mother of pearl bead rosary with handcut oblong beads measuring between 5mm and 7mm. The center medal appears to be silver plated brass. The connector chain between the decades are silvertone and the tiny and beautifully looped wire connectors formed by the boys appear to be copper, but they may be brass. 

The center medal features The Virgin Mary with a sunburst on one side with the Sacred Heart of Jesus on the back. The crucifix is wood with metal capping, and is engraved on the back BLIND BOYS SCHOOL DRUMCONDRA.  This is the first rosary I have seen from this school. 

Rosary is from the 1950's, is in found condition, and has not been cleaned. All beads are present. 

Below is a photo from a 'Souvenir Booklet' made in 1958, showing some of the boys learning to make the rosaries.
