The Bloch Physiograph is an early camera offered by the French maker Bloch. Specific specifications, format and introduction date for this model are not documented in the data provided here.

Auction data for the Bloch Physiograph is extremely limited: a single UK saleroom hammer result from May 2005 records a price of £840, which is the only reference point available for what this camera sells for. With just one auction record on file, it is not possible to define a reliable price range or median value at today's market level, and the figure shown reflects a wholesale hammer result rather than a retail asking price.
