T-REX Metal Guru (Rare Uncut test pressing disc of the crouched Marc 'shaped picture disc'. This superb rarity has not been cut to the finished shape but remains as a 12" disc with clear surround around the central image. Uncut picture discs are generally used as test pressings, a few are always made to check the image alignment & print quality before the final run is cut to the desired shape. This example has a 'tea-stained' appearance, this happened often to pressings of thistype from the 1980s. During the pressing process they were over heated, over time the clear area of the disc changes colour to a smokey brown, however this has no effect on play PTANX1)
