[Ticket to a concert "For the benefit of Mr. Guadagni"].

Image depicts a (slightly reimagined) episdode from Act 1, Scene 2, of Gluck's Orfeo ed Euridice. From left to right: A cherub (Cupid?) with a torch; and Orpheus (with a violin(?)) and Eurydice fleeing Cerberus, the multiheaded guard dog, tearing at their clothes.
An engraving by F. Bartolozzi after a drawing by G. B. Cipriani.
Possibly for the benefit concert for Gaetano Guadagni at the King's Theater (London) on 16 March 1769.
Guadagni created the role of Orfeo (1762) and sang the first Orfeos in London (1770-1771).
