Stanhope, the medium hidden in a pen
When I was a primary school student in the early 1980s, my friend Lisa brought a strange pen to school. There was a tiny hole at the end of the pen, into which, when glanced, erotic images with content incompatible with socialism appeared. It had a rotating ring, which meant that several enlightening slides appeared when a tiny ring was wound around it. At the time, I had no idea that I was holding the last reminder of a fashion that was almost 100 years old.
