A drawing of a naked bearded man blowing a long curved horn, and holding another; standing at his feet, two putti, one of whom blows on another horn while holding a cornucopia in his left arm. 

The drawing appears to be a copy after an original by Parmigianino, recorded in the inventory of Roberto Canonici, 1632: 'Un huomo nudo, che suona una tromba, e ne tiene un'altra in mano, ha duoi putini appresso nudi, e a in mano un cornucopia, del Parmiggiano' (G. Campori, Cataloghi ed inventarii inediti, Modena 1870, p. 126). 

The style of the penwork is unlike Parmigianino's, and may even be German.
