Please email me directly at the email address found on the bottom of Don's webpage. I will need some details with regards to these cels. If you can email me pictures of the cels, I can (for example) locate WHICH of the Lizard King hallway sequences you're asking about. Also, most importantly, we will need the measurements of your cel in order to issue a proper estimate. A 16 field cel (approx 13 x 16) will require a larger painting which will take more time and therefore, cost more than a background for 12 field (10x12) cel. Also, with regards to a pan background, if your cel is a wide pan sheet of celluloid, then a pan background to match is appropriate. However, if your cel is still only a 10x12 cel, then it is wise to just have a 10x12 background painted for it since that would be the framable area. It is problematic to frame a cel to a much larger background.
Please contact me directly with either some jpeg images of the cels you're inquiring about (or some links to some images you have posted online) along with those measurements and we can get some estimates to you. We look forward to hearing from you soon.
