“Every number of Camera Work was published complete when issued. The way it happens that plates are missing is that frequently Camera Work came out of the bindery with plates to be inserted by me personally after binding. Some years ago many of the insets were either destroyed or mislaid. Hence the impossibility of completing many issues at present I know of no way of acquiring missing plates except in keeping one’s eyes open for numbers of Camera Work as they may appear in the market. Absolutely complete sets of Camera Work are very, very rare & are priceless. No I have no reproductions either, there are none. The Plates in Camera Work for the major part are photogravures made directly from original negatives & were made under my direction as were the prints. -So from a certain point of view many of the Plates might be looked upon as a species of originals".
