The following book is now available on-line in PDF:
Henry Baker Tristram [1822-1906], The Land of Moab. Travels and Discoveries on the East Side of the Dead Sea and the Jordan. London: John Murray, 1873. Hbk. pp.408. [This material is in the Public Domain]
The book contains over 40 pen and ink illustrations dating from the 1870’s which show the landscape of Moab. I have scanned each of these individually and provided them in a variety of resolutions for re-use.
