I think it's an open matte (flat) one, which is rare. (to me, anyways)
Hopefully, someone purchases it, scans all of the reels, and (hopefully) uploads it to Internet Archive.
Although, now that I think about it, I wonder if anyone has 35mm prints of The Powerpuff Girls Movie, and the Dexter's Laboratory short that played before this film, “Chicken Scratch”...
