Official seals are unique emblems or stamps used by governments, organizations, or institutions to authenticate documents and signify their legitimacy. These seals often include symbols, logos, or text that represent the authority of the issuing body. They are commonly found on legal documents, certificates, and official correspondence. The use of official seals dates back centuries and serves to prevent forgery and ensure trust in the authenticity of important papers. In many cases, the presence of a seal indicates that a document has been reviewed and approved by a specific authority, such as a government agency or educational institution.
