This is a set of 5 phone cards entitled the Old Singapore.
Designs include photographs of Clifford Pier, Fullerton Building, Collyer Quay, Raffles place and Empress Place.
If you look at the back of the phone-cards, they all have a serial number of 000767 and are unused.
This is a full set and was bought at $120 dollars back in May 1993. It has been well kept and it could be the last set in existence. :)
