The four employees in the photo are surrounded by large stacks of tickets. They are probably WarCo volunteers. The War Comforts Fund Association (WarCo) provided relief for the victims of air raids. It also raised money for cigarettes to send to servicemen, and its members knitted clothing for them.
At its peak there were 12,000 L.T. staff, men as well as women, knitting for WarCo. Of the four women here, the two on the right are winding a ball of wool, while the two on the left are knitting.
