The photograph above appeared in the
Amateur Photographer's Library - Booklet No.8 - Carbon Printing,
as an example of a Carbon Print.
It was printed by Elliott &
Son on their Carbon tissue, and was described as a "Hand Camera Shot".
It was taken on one of Elliott & Son's "Barnet" Extra Rapid Plates.
Booklet No 8 - Carbon Printing was published in 1894.
Convention of the United Kingdom had their Annual Convention in
Edinburgh two years earlier, in the summer of 1892. Was this
photograph of Musselburgh Fishwives, perhaps, taken by one of the
delegates to that Convention?
