Another Phegor drawing. German, 1930s. Anyone know anything about him?

I’ve been sent another Phegor drawing. It’s got some things in common with his other drawing, which I featured in the post “Radclyffe Hall with a whip”.

He (I’m assuming Phegor was a man) put boots on his dommes, and drew those boots in some detail. He liked stockings, too. And, obviously, he really liked drawing whip marks. The title, “Die Geisel der Freundin” (“The Girlfriend’s Whip”), suggests that he was German, but it may just be that this post card, or book illustration, was printed in Germany.

Thanks to the donor of this other Phegor drawing. Does anyone know any more about this artist? Actual name, other pseudonyms, anything?
