*cough cough*

I used to be a museum curator, so I've had plenty 
of fun trying to figure out nondestructive ways 
of exhibiting things. ;o) I'm personally afraid 
of framing my own cels-- all this talk of line 
fading has me scared to-- but this is how I would 
frame my cel if I had to.

You'd probably want to go with an open-corner 
mount, stick them to some sort of backing board 
(ie, something stiff and acid-free), and then 
insert the cel itself into the mounts. That way, 
the corners keep the cel in place for framing, 
without causing irreparable damage. It would 
probably be matted, to keep the glass from 
pressing up directly against the cel itself (that 
will hopefully lessen the likelihood of the cel 
sticking to the backing; of course, you should 
probably put some sort of layer between the cel's 
backside and the backing it's mounted on). And 
the glass itself would probably filter out UV 
radiation, which will help minimize fading-- 
although, from some of the threads here, your 
mileage may vary. And you wouldn't want to hang 
it in direct sunlight (heat, light) and all that 
good stuff, but I'm digressing. :o)

In general, if you don't have the skills to 
mount, mat, and frame the cel yourself, and you 
don't want to stand over their shoulder to make 
sure they don't destroy your cel in the process, 
go to a reputable gallery, like one that sells 
real art. ^_^ They usually provide framing 
services, and pretty much *have* to be reliable 
to stay in business. If you're queasy about it, 
your only other real option is to go to a place 
like Hobby Lobby or Michaels, or some other craft 
store that does framing, and hope that the high-
school kid who runs the glass cutter also knows 
something about art, and how to treat it 
properly. ;o)

But if you're not doing your own work, I'd 
probably go with a real dealer, as opposed to a 
place that sells art off the rack.
