What does the BOC logo mean?

We like to say it is an ancient symbol that means "Blue Oyster Cult".

The BOC logo was created by Bill Gawlik, the artist who created the band's first and second album covers. It is a stylization of the astronomical symbol for the planet Saturn. In the process of creating the album cover, Gawlick used a washer to separate the symbol into its 5 parts hook, bars and dot.

When the band was shown the artwork for the album cover, they instantly decided that it would be the perfect band logo, and that it is.
