What a wonderful and rare set of early cards.
Ephemera is not at all my expertise but these cards I found so charming.
They date from the very early 1800s , the wonderful characatures depicted are so typical of this period. The cards look to be lithographed and hand coloured.
Altthough a little dirty with age they are all in really great condition and I woud think it very rare to find such a large set.
