Tuffy is correct.
The Expo 7-16 catalogue was published by Hagemann therefore it is safe to say that Expo 1-16 were not CCC. There was also an Expo 1-6 catalogue with no publishers name.
After years and years of searching for these ultra-rare items, a copy of both popped through my letterbox today which means I know all the previously-unknown early Expo Film titles
however at great financial cost
.
Stills from some of the films were used for various early mags, definitely Color Orgasm and maybe Color Sperma. I'll check which issues have been posted here.
Mod alert
This thread could be moved out of Other Requests to somewhere more appropriate. A better title would be
Expo Films 1-16 as they are not CC and good eyesight not needed anymore!
