This lovely image of the possibilities of future aerial flight was made by the celebrated caricaturist and illustrator George Cruikshank, and was printed in 1836. The aircraft at top is a massive affair (the selling of the “beautiful Castle in St. Cloud”) offered great possibilities along with “no ground rent”. It is absolutely a castle int he sky, literally and figuratively, and must’ve seemed to be something of a possibility to Cruikshank in the fifth decade following the first balloon ascension. Of course he was having a turn at aviation, but I think he also saw the bits of the feasible within his hopeful caricatures.
