Delville Magnetic Ko-Type Desk Telephone

From December of the thirtieth year of the Meiji Period (1897), the first desk telephones were of two kinds, the Delville magnetic ko-type and otsu-type. In those days, they were called epoch-making. They not only increased the practical use of the telephone but also were designed carefully to be used as decoration. From around that time, the demand for the telephone continued to increase and even advertisements for buying and selling telephones were placed in railroad coaches. Incidentally, the annual rate of added use was 6 yen.
