A poster advertising Green's thirtieth balloon ascent from Nuns' Field in Newcastle on 23 May 1825. Charles Green (1785-1870) was one of the greatest English aeronauts and also pioneered the use of coal-gas - a cheaper alternative to hydrogen - in balloons. He made his first ascent, and the first ever to be made with coal-gas, on 19 July 1821, in a balloon called 'George IV Royal Coronation Balloon' in celebration of King George IV's (1762-1830) coronation. Green went on to make over 200 ascents in this balloon and its similar succesor. This ascent was probably made in the original Coronation balloon. The poster states that the balloon was made from a thousand yards of gold and crimson silk and could hold up to 22,698 cubic feet of gas.
