By 1872, the electric telegraph made its debut in Manila. Two years later, telegraph stamps were used by the public to prepay for this service. Under Spanish rule, postal and telegraph services were integrated into one office called the General Administration for Communications. As a result, postage and revenue stamps were indiscriminately used by postal clerks on telegraph receipts, while telegraph stamps and “cancels” were also used on mail. This huge, hand-drawn map details each telegraph station that was to be set up in the country. (Contributed)
