On ebay: An issue of The Gentlemen’s Magazine from June 1770, which contains two small blurbs about the marriage of Louis XVI and Marie Antoinette:
The King and dauphin of France had the first interview with the young dauphiness. They met at the bridge of Berne in the forest of Compeigne, and their first salutation was very tender and affecting.
The ceremony of the nuptials of the dauphin and dauphiness at the chapel royal at Versailles by the archbishop of Rheims. After supper, the king having conducted their highnesses to their apartment, and the benediction of the bed having been made by the archbishop, the king delivered the shirt to the dauphin, and the duchess of Chartres, performed the same office to the dauphiness.
