The origin of the loops is not clear, but my belief is that they were created for Le Salon. They were marketed by several distributors, including Mustang/Falcon. When the films were put on a compilation videotape around 1981, the loops were attributed to Rollo Productions, but the loops and tape were marketed by Le Salon. The series of loops has a general theme of "working men" (physical laborers and repairmen) having sex. In the late seventies, it was common for loops to be marketed as a series (usually of six). Often, the only thing in common between the loops in a series was a theme. Stills from these loops were marketed by Le Salon, as "Pantheon" mags, and the photographers for Pantheon included Adam Cadman, Colin Meyer, D.J. Garrett and Ned Hart (Fred Bisonnes). At about the same time, Fred Bisonnes and Carlos Quiroz were creating a series of mags for Le Salon marketed as "Western Man" mags. Subsequently, the in-house studio for Le Salon was known as Lobo Studios.
