Wine glass with three music-making boys, Anonymous, c. 1775 - c. 1798
Engraver David Wolff specialized in representations of themes such as friendship, freedom or – in this case – harmony. His glasses feature scenes of boys dancing, playing or making music. Because Wolff used little contrast in his work, it was sometimes difficult to read his highly sophisticated scenes. However, they became clear as soon as the glass was filled with red wine.
