This is the Sevans Prototype/Promotional Box Art Dalek
If bought a famous Sevans Dalek kit to build, then you more than likely picked up a Sevans kit with a Gold Dalek appearing on the front of the box, this is that Dalek ! An iconic piece of Doctor Who history, with provenance in photo matching the dalek in lots of areas, a TBT Props Matthew Doe COA and letter from Stuart Evans.
Comes complete with original photographs from the photoshoot also. A fine piece of art and only one in existence used for this cover shoot.
