Some of the "porn" distributed by Michael Thevis, Robert DiBernardo & Reuben Sturman: Eros/Goldstripe & Pain Library Classics (PLC) ran under Pendulum Books & Star Distributors, Inc.
Star Distributors had a separate imprint, 'Satan's Library', focusing on occult sadism/torture.
Michael Thevis was also campaign treasurer for Georgia Klan Dragon Calvin Craig during his race for Fulton County Sheriff in 1969. Another (seemingly) disparate Klan connection to the Atlanta Child Murders.
