In Katr, when I was leafing through my Vitalis edition of Kafka's drawings, I came across the picture of a 'Grumpy Man in Black Suit' that the editors have placed alongside the following excerpt from his diaries:
Then suddenly we see Löwy, who had seemed to have vanished, being pushed towards a door by head waiter Roubitschek with his hands and possibly also his knees. He was simply to be thrown out. This head waiter, who stands like a dog in front of every guest, including us earlier and later on, with a dog-like nose which sinks over a large mouth closed by humble jowls. [Diary, 14th October 1911]
An image, of course, which I left clearly visible on the table for a short while.
