Here is the holy grail of promotional displays. This impressive, three-dimensional cardboard display stands approximately 35.75″ x 27.5″. This imposing display was used in record stores in the United States to advertise Physical Graffiti. This display consists of two attached pieces with an easel backing.
Due to the size and age of this display, they are very hard to find, let alone finding them in decent condition. They usually show a lot of wear and have damaged corners.
A bonus rarity would be the instruction sheet that comes with this piece.
