Coloured lithograph by Zannoli & Co after an original design by G Meloni. The Italian Muzio Muzzi's design for an aerial machine, the 'Retirremiga', consisted of a hot-air balloon heated with a Davy lamp and attached to two large propellers. Muzzi was granted a patent for this, or a similar design on 12 May 1844. Dimensions: 470mm x 648mm.
