Here is another example of early photos (claimed to be 1840-1850..) some are looking like drawn in (in Russian language). Quite an interesting book:
1842-1851-1901. Nikolaev railway. Part 1.
Here is some more info about that dig that I've found:
DPG Media Privacy Gate -photos clickable
De Huidevetterstoren van de Spaanse Omwalling in Antwerpen
SIAM 19 - this one is the most interesting, with lots of pictures but in form of a PDF presentation that I could not download, maybe someone...
