if you regard the bonus material of the English MGM DVD Special Edition you find some black and white photos of cutted scenes which Leone maybe cutted out of the final movie. These are the scenes in Indios lair, when Indios gang and Eastwood hang around with women.
There are also cinema photos existing where Clint and Klaus Kinski walking on top of a roof with colts in hand. These are pretty cool photos of Kinski also there are photos where you can see Kinski riding on a horse with a long cape and another picture where he wears a big round hat and smoking a cigarette with rising dust.
Another photo shows Lee Van Cleef riding into town, this scene also doesn't exist in the actual movie.
Not to forget the cutted scene with Eastwood and the hotel woman/prostitude in the hotel room of Eastwood.
Such a pitty these scenes where cut by Leone or the producers.
