Orion: "Sex zu Zweit" 1988

The "Christine Le Duc" Erotic Shops Chain published a series of booklets (15x10cm ca, 6x4") labeled Orion. The size allows you to keep it in your inside pocket, so really a "pocket book" you can take with you to the men's (or ladies'!) room.
The oldest I have is of 1988 and is called "Sex zu Zweit," Sex the two of them/us?;).
This first one had 110 (!) pages in it, I scanned the double pages for you. Enjoy them.
