J. F. Calverto
Glasgow-based variety agent and concert-party manager. Calverto ran his own touring concert parties in the North, appearing, for example, in Lerwick, Shetland, in 1896 as 'The Man with Mysterious Fingers', returning in 1897 with Vitagraph animated pictures, and in 1898 with the Operaphone when he also visited Tain, Beauly, Fort William, Ballachulish, Oban, Tobermory and Easdale. On a tour of Lerwick, Fort William, Tobermory and Oban in 1900, he brought images of the 'actual fighting' in the Boer War. Calverto also hired out equipment to other entertainers.
