They aren’t! However some of these premium retailers do have their designer make some or use fan art. Take the on masterpiece collection of dusk till dawn. The 2 full slips used aren’t poster art. Their designers have used images and made a design around it. FAC used @Noodles design for wolf of Wall Street. The homecoming wwa and new far from home wwa illustrated steels are from artists.Why do people always talk Like Manta or Zavvi, hmv or whoever came up with the design? Its fox/disney property they would have designed it and obviously decided to use a previous design :—)
Took the words right out of my mouth... you know you're doing something right if others copy your work.
