One of a series of colour etchings published by T McLean of Haymarket, London. Paul Pry's 'March of Intellect' series of satirical prints was published between 1825 and 1829, lampooning the political isues and reading habits of the day. Here, fantastic imaginary inventions are shown, including tunnels to the North Pole and South America, a flame that will roast an ox but is harmles to children, and a 'grand cigar divan' which produces condensed smoke. The layout is that of a travelling show, or circus, featuring various acts and novelties.
