This is a postcard from Marie Helena Martin (1892-1975) to Miss Martin in Dublin. Marie Martin, later known as 'Mother Mary', was a volunteer nurse during the First World War. She served in field hospitals in Malta, Leeds, and France working for the British army and later went on to become the founder of the Medical Missionaries of Mary (MMM). This postcard shows Maries place of work and Marie was simply letting the recipient know she was safe.
