The promotional poster sketch

The other piece of SilverHawks production material in the Heritage archive is not from an episode at all. It is sketch work for a promotional poster, sold as a lot of two items and catalogued to Rankin/Bass in 1986.

Promotional art sits in an awkward place for a collector. It was made to sell the show rather than to be the show, so it never went under a camera and never became a frame anybody watched. What it does carry is a stage of the design that the finished series does not: somebody working out how the five of them stand together before that arrangement got fixed.

Heritage file it under production cels, which is a shelving decision rather than a description. The lot is sketch material.
