I have a 45 Promo copy of Stairway to Heaven. It is a Hi Records distributed
by London. It is a Promotion Copy (printed on top) on an all white label,
which also says Not For Sale on the side. There is no band name,
there is no song name printed on it, and no company label.
It's 'scratch' label says Promo ll side l and Promo ll side ll.
