In the Bridgerton family, or Jane Austen’s household, and during the Regency Era, sealing wax was not only impressed onto the back of a letter with a seal to protect against tampering, but also to identify the sender of the letter. People, especially aristocrats, kept personal and family seals to be used for many different purposes e.g. A letter to a government official would be sealed with an aristocrat’s crest or title. Personal seals for identification have been since early civilizations. The rubber stamps and embossers we use today serve the same purpose, identifying the sender.
