Montgolfier balloon (model), Science Museum
Only six years before the French revolution Montgolfier brothers flew full size of this hot air balloon in Versailles. The first flight carried three animals – the rooster, the duck and the sheep, and was flown in front of the eyes of Marie Antoinette, Louis XVI and the French Court. Somewhere else I read that inflatables and revolution chime well alluding to the forthcoming abolition (and execution) of French monarchy.
