Singapore
D.L.O. Label

This aerogramme form, “Form Approved by the Postmaster General Malaya No. 25 (1)", was sent from Singapore to Karachi, Pakistan in 1959.

Several Karachi post offices tried to deliver the aerogramme as can be seen from three arrival cancels of post offices (2 SEP 59, 4 SEP 59 and 8 SEP 59) on the back panel. 

Finally, the Dead Letter Office was successful in identifying the correct address. A label with this address and the h/s “D.L.O. Karachi” was affixed to the front panel.
