AC/DC "BACK IN BLACK" LP - On ATLANTIC Records, SD 16018. Original 1980 USA stereo pressing . RARE PROMOTIONAL COPY! The promotional gold stamp & timing strip on the cover clearly identifies the item as promotional. Has the “MASTERDISK” stamp in the trail-off vinyl (dead wax) area, which is generally considered a proof of authenticity of the first pressing. In the trail-off wax, there is also an etching that says “RL”. Robert Ludwig only mastered a few of these records, so his top-notch work on Back in Black is very rare.
