These are the only four rings that Leatherface (Andrew Bryniarski)wore throughout the entire film. These screen matched rings can be easily seen during any scene of the film where Andrews hands are visible. The most identified ring is the silver ram head, which are clearly visible on any Leatherface hand shot with or without the chainsaw.
This group of four rings came directly from Newline Cinema in 2003 during the Texas Chainsaw Massacre auctions.
