I do:)  My mother collects cels as well.  As a 
matter of fact, she bought me one of my favourite 
cels in '98 when I got my first "real" job.  ^_^
This is Nova from Magic Knight RayEarth II.



However the flip side is that she now has some of 
my favourite cels.  ^^;;  I also bought her a 
Last Unicorn cel for Christmas that she started 
to cry when she unwrapped it.  ^_^

I knew I converted her a few years ago when we 
were watching Fushigi Yuugi & she saw this still 
shot of Hotohori & said "WOW!  That would be an 
awesome cel to own"  :D
