The familiar 'To Mary in Heaven' scroll.
At the base is the name of the sculptor, Sir John Steell of Edinburgh. The date is 1886, whereas Steell's statues in Central Park, New York City and the Victoria Embankment Gardens, London, date from 1880 and 1884 respectively.
There is a link below to my photos of the other statues.
