Why should we know an anime and have watched it
to collect cels from it ?!? Some people collect 
cels for the cels themseves and not for the anime 
they are from.

When I started collecting, I bought quite a lot of 
cels without knowing anything about which anime 
they are from. It's only much later that I watched 
the anime. (And I am also collecting cels from 
anime that I don't like : It's not because I like 
the design of an anime that I have to like the 
anime itself)
