It feels like I find at least a few mistakes every week or
so with Ranma and Dragonball cels. I always email the 
seller with a "heads-up", but most don't change their
descriptions. ie-some of you might remember a dragonball
cel that used a description like "WOW! GOKU'S BUTT!!!"
and started the cel at $75. It circled the list a few times
before they either gave up or some poor shmuck actually
bid. It wasn't Goku, at least not the one we're all thinking
of. It's his great-great-great grandkid also named Goku from
one of the movies. So, either they didn't care about the
innacuracy of were purposely misleading the bidder. 
But some sellers do appreciate the help and end up changing
their descriptions. I think it's a good idea to get in
touch with dealers who don't fully understand their product.
Because, unfortunately, just because they are selling
a product, doesn't mean they know much about it.
