The Rehearsal

If Baldur von Schirach were a woman, he'd probably be a radical feminist. He encouraged girls to take up unfeminine sports and believed that models should march instead of, well, walking like models.
Ironically, he was often mocked for effeminacy by his fellow Nazis. Poor genderqueer von Schirach.

The singing lady is his elder sister Rosalind, a once famous opera soprano.
