I stumbled upon this after hearing from BBC this morning. The UK govt has many more pictures to release to the public. Amazing pictures with the then modern photographic equipment... I really admire the skills of those photographers. They release Africa through a lens, later they will go to other parts of the British colonies. Singapore is certainly include.
