I have another option for a similar "look".
I used a reproduction Cel of Rei from Neon Genesis Evengelion (theres no way I'd use a $200+ original,
).
I just cut out the background (was blue sky) and applied it to 1/8" Lexan. Static cling holds it on there quite well for demonstration purposes until I get the window cut & mount it. The cut out area will show through to the inside of the case. Case interior lighted, which will of course back light the cel.
Here it is against my monitor
And against a case:
Low quality, but I only have a webcam for now
