The Master and Margarita
From the album “Three artworks by Gustaf Öhrnell Hjalmars”
Margarita flying on a boar. Yes, I remember that it was actually her maid Natasha who was flying on a boar, but it's unlikely the artist would have paid so much attention to the maid when he didn't draw Margarita's flight at all, did he? However, if you decide that it's Natasha after all, I won't object.
On the roof of one of the houses, by the way, you can see Koroviev and Behemoth watching her.
