Others are a bit more puzzling, and one in particular really has me curious: Love Cave, whose amusingly literal title makes for an awesomely filthy double-entendre. (Or I just have the mentality of a seventh grader. Your call.) It's actually rougher looking than the rest; its name conjurs up a different image than the photos represent, but I don't know if Rape Cave would've gone over very well.
The second still down actually isn't mine; I found it at One Sheet Index and have included it here (reframed and cleaned up) for completeness.
John Charles sent along a newspaper ad for Love Cave, paired with something called Under Cover Girls, from the July 11, 1975 edition of The Toronto Star.
