I've seen 2 instances of an octahedron white and grey marble being sold on ebay (https://www.popsike.com/The-Mars-Volta-Octahedron-2x-LP-Vinyl-WHITE-GRAY-New/251978134711.html and https://www.popsike.com/The-Mars-Volta-Octahedron-2xlp-vinyl-GREY-WHITE-color-vinyl/322237305309.html)
If anyone has one of these or knows where I can get one, I'm willing to pay a good price for it.
Also, I know a bunch of the Octahedron records have been sold as black vinyl copies, but I have NEVER actually seen even a picture of a black Octahedron copy, unless it was a test press.
Any info / help would be greatly appreciated.
