Over the decades, many witnesses of UFOs did not report seeing actual flying machines. Rather, they reported seeing unusual and/or brightly colored lights in the sky.
In some cases, their experiences inspired them to reproduce these lights in the form of drawing and paintings.
What you see here are some drawings and watercolors made by residents in the Soviet Union in 1989. Among other things, I think they demonstrate that the aesthetic aspects of the UFO phenomenon have been all-too-often neglected by those studying it.
