6. Sepia Cards
Small series of 20 cards. These sepia cards were printed in France by Albert Bergeret at Imprimeries Réunies de Nancy. Some cards do not have Rochat's name on it but could be easily identified by the printing style and the printer's name. Earliest found used: September 1916. Given the timing of the 1st World War, it is likely that these were printed before Ottoman Empire joined the war in 1915.
