More on 18th Century Letters.

For general mail in the 18th century there were no envelopes. Letters were written on one side only and then folded to form an envelope. All the examles I have found so far have been sealed with sealing wax, though I can only assume that letters were tied with cord or ribbon if sealing wax was not available. This needs more research.
