Dawn.com collaborates with the Citizens Archive of Pakistan (CAP) to bring you a series of images from our country's history. Rare glimpses of yesterday's life, familiar places as they used to be, and frozen memories from times past.

This set of photographs from May 11, 1956 beautifully documents a busy "ice factory" in Lahore. Workers toil with heavy machinery, twist valves and pull chains to produce large blocks of precious ice. They then load them onto horse drawn "tongas" to be transported and sold. - Photos from CAP/shot & donated by FE Chaudry
