This one turned out to be even lovelier than the 
scan of it.

Another one that turned out better in person was 
a cel from the Violinist of Hamelin. It's a cel 
that's on practically every site -- Flute's in 
the foreground and Hamelin's in the back. It's a 
low light cel, but there's something appealing 
about how the white turns into light blue, and 
the pink into a deeper colour.
