Individual letter package from the Music category of Arts in Letters, featuring Italian composer Antonio Vivaldi. You'll receive a transcription of an actual letter written by Vivaldi to a local aristocrat, asking for help getting approval to travel to the premiere of a new opera he composed, accompanied by biographical and background information and images of their works, mailed to you in a letter envelope. This letter package was previously sent to subscribers and will not be sent out again. Letters ordered by Wednesday at midnight CST will be sent out Saturday, with our regular weekly mailing.
