Columbia Records, double-ended, full colour promotional counter display which would have been used in U.S. record shops to promote the VHS release of The Line, The Cross & The Curve.
It measures 16" in length with a width of 5.5". It folds into a triangular shape and is held together by a sticky strip on the back. Mine has never been folded or stuck together, and I'm not about to do that. However, if this had been folded, it would have a resting height of nearly 7". It's also made from a thinner type of card stock, so it wouldn't take much to destroy this thing.
I've seen this one turn up a few times here and there, so it's still out there. Typically you will find these in a used or beat up condition when they do turn up.
