Great topic joyka!! I appreciate several of my
backgrounds just as much as my cels.
Here's one of my favorites. It's Crystal Toyko
from the R season of Sailor Moon. I just love
the color and detail. Many SM collectors will
recognise this one - the dealer that sold it to
me made several laser copies.
As far as I know, there is no cel that matches
this background. The one scene I remember seeing
it in just showed the background alone.
