Nuns teaching in a convent girls’ school feature regularly in Wilder’s output; whether this is pure fantasy or has a basis in experience is unclear, but nuns with their uncertain and mysterious sexuality have always been at the centre of erotic imagery.

As with so many of Wilder’s drawings, it is clear that the artist identifies strongly with the bespectacled girl in the tartan skirt, who sports both well-developed nubile breasts and a ready-for-action cock.
