The last pic is very close to the colors of the old italian DVD of GBU.
Well, I don't know whether it is the lack of color correction to a carbon arc light source or the print has been damaged, but it looks like there is to much magenta in the first pics.
Despite the fact, that the film restorer posted this comparison, the colors of his restaurations of the first dollar movies look more like mondo.
I personaly prefer the colors of the mondo Blu-ray, but I am very excited how your print will look like, when it is color corrected to a carbon arc.
