A goolie chit was originally known as a blood chit. It is a notice carried by military personnel and addressed to any civilians who may come across an armed-services member – such as a shot-down pilot – in difficulties. As well as identifying the force to which the bearer belongs as friendly, the notice displays a message requesting that the service member be rendered every assistance. The gold sovereigns were intended as an added ’incentive’ to anyone assisting the aircrew.
