The Royal Air Force Aircraft Exhibition was held at Roundhay Park in the late spring of 1919 and boasted an outstanding collection of aircraft and artefacts. Its aim was to give the public an idea of the advances made in aerial warfare and technical aeronautical matters, as well as to augment the funds of RAF charities. The public at this time were still greatly excited by aviation and the chance to view the 20 British planes on display just seven months after the Armistice proved popular. The exhibition also offered the first ever chance for members of the public to make ascents in a military balloon. These photos showcase what was on offer to visitors and are published courtesy of photographic archive Leodis, which is run by Leeds Library & Information Service. They also run heritage blog The Secret Library Leeds, which provides a behind the scenes look at the Central Library and highlights from its special collections, including rare books hidden away in the stacks.
