Murphy's signals Hobart Town : the colonial ship flags and semaphore signal charts of convict guard Pte Edward Murphy, 99th Regiment of Foot, Van Dieman's Land /Mark L. Risby.

"Murphy's signal charts represent some of the most significant historical maritime art of Tasmania, produced by an untrained draughtsman in the remote island penal colony during the 1840s and 1850s. These charts contain the only known drawings of the merchant ships' Van Diemen's Land Colonial Ensign and the entire collection of the individual merchant ships identification flags flown in old Hobart Town. Bringing together all the known signal flag charts drawn by Murphy for the first time, this fascinating book shows in fine detail the 250 different flags and over 300 telegraphic semaphore signals and their decodes. Lavishly illustrated and well researched, this book is an ideal addition to the bookshelves of anyone interested in vexillology, art, maritime history and general Tasmanian and Australian history."--Back cover.
