My copy has D.J. COPY, (BOTH SIDES)
Would have thought most have.
I wonder if it was a test run at the printers for the Stock Copy using Existing Label Blanks
which just happened to be the Grey / White as used for the DEMO.
Or at change over from printing one design to the other and a rogue sheet of Label Blanks mixed in.
I have the same theory regarding this one below. A quick print to check for Layout etc but using existing or scrap paper.
The Gordy below flipped on it's side to allow for the Gordy Arrow Logo.
Never Intended to be used.
Then used in error.
We have probably all seen the DEMOs with Promotional, DJ Copy or NOT FOR SALE rubbed out.
Obviously as a collector, never tried it but would imagine it's difficult to leave no trace on a two tone albeit grey / white label.
