An on-line catalogue of the Egyptian drawings by William John Bankes' can now be accessed via the Dorset History Centre. The images were created by Bankes and his party between 1815 and 1822.
Thanks to Early Explorers in Egypt and Nubia for this information and the following suggestion:
"As the catalogue does not have a page on its own, it must be reached through a query: the keywords suggested are “Egyptian Drawings”. Photos are not available on-line yet, but on request the Dorset History Centre can provide a digital image of the documents"
