Satanist Themes in Movie

I just saw this movie on the DVD, and I was surprised to see some images/symbols of satanism back in this 1965 movie, specifically:
1. When he is in the library, the librarian hands him the book "Magic and Supernatural" by Bessie, the source for the today well-known inverted pentagram with goat and Hebrew letters, and it is seen clearly on the cover of the book in the movie. (This same image would return a few years later in Hammer Vampire movies of the late 60s early 70s). Too bad the satanist themselves didn't use the symbol (they used a 6 pointed star instead).
2. The book on talismans (from the library) shows clearly a left hand displaying the "sign of the horns".
3. Black candles.

No inverted crosses, but the Vincent Price movie from a year earlier "Masque of the Red Death" has them. (As well as black candles).
