Hi~!

I recently got a very nice cel from a friend, but 
when I received it it had a small crack and a 
little bending in the top left hand corner. I was 
just wondering if there is anything I can do to 
fix and/or bind it so that it looks better.  It's 
such a nice cel, so I'm rather dismayed at the 
crack. I was thinking of using clear acrylic 
paint or something of the like, but I was just 
wondering if that would take away from the value 
of the cel or make it look even worse. Actually, 
the value isn't quite as important, since I 
probably won't be selling it, but I would like it 
to look better. If anyone could help me, I'd 
really appreciate it. Thanks a lot!

P.S. I'm including a picture. You can kind of see 
the cracks, but there is some bending too. Is 
there anything I can do?
