This here ad dates back to Halloween time in 1984, and was placed in Fangoria Magazine to promote two new lines of Don Post masks based on two movies that had recently been released at the time; An American Werewolf In London & The Last Starfighter. So rare have the American Werewolf masks become in recent years that it was only a few months back that I even knew of their existence, and have since finding out about them only found one set on eBay, which had a starting price of a whopping $500! The auction received no bids, but that asking price combined with the fact that you rarely see these things around lets you know how rare they are.
What's interesting about these masks, sculpted using Rick Baker's original head pieces as guides, is that the whole line is based on the brief Nazi/werewolf/demon nightmare sequence in the film. While a totally awesome scene that is still highly memorable to this day, you'd expect Don Post to go with something a bit more marketable and reflective of the overall feel of the film, like the David wolf or a torn up Jack. So ya gotta give props to the company for taking the chance to do something a little more outside of the box with the movie license. Very rarely do you ever see big time mask companies putting out masks based on side characters from films, so these are pretty awesome, which is probably why they're so sought after and hard to find!
