Hey there,
This symbol has been following me for years and I have no idea what it means!
I found this image on the cover of a book but I dont have the book so I can't read into it.
Any help would be great. Thanks.

It's the cover of Curses, Hexes & Crossing: A Magician's Guide to Execration Magick by S. Connolly-

It doesn't say in the book what the symbol means, The best thing would be to email him or his publisher.
