Yes it's a similar factory package to boost sales in 1967. Like the 1966-67 HCS cars the Ski Country Specials came with a special emblem and in limited colors named (appropriately enough) after local Colorado ski resorts; Vail Blue, Aspen Red, Loveland Green, Breckenridge Yellow or Winter Park Turquoise. They also came with a few other extras like ski racks, snow tires, posi rear diffs and coffee bar. (still never seen a photo of this coffee bar. I'm envisioning a cup holder! :cheesy: )
Unlike the 66-67 HCS package, the Ski Country could also be ordered on other Fords; Mustang, Galaxie, Fairlane & Country Sedan. There's been rumors about it also being offered on Broncos, which makes perfect sense, but I've never seen any proof of this so I'm not convinced.
Here are some links for more info.

That particular car has been for sale for quite a while, both on ebay and craigslist. The owner has a Marti Report and another piece of documentation, but the photos of these are so poor you can't read anything. I'd love to see clearly scanned versions, as well as a readable pic of the door data plate.
