A printed handbill advertising Richard Gypson's 40th balloon ascent from the gasworks at Wisbech, Cambridgeshire, on Thursday 12 August 1841. For this ascent, Gypson used a balloon made from 1,800 yards (1646 m) of crimson and gold silk. It was 60 feet high and contained 20,000 cubic feet of gas. During the ascent, Gypson released a parachute containing a live animal. He also intended to take several pasengers with him in the balloon. The advert asures the public that it is perfectly safe because Gypson has already 'had the honor (sic) of conveying three ladies and twenty nine gentlemen safely to terra firma'. Printed by John Leach, Wisbech.
