I have the maroon and yellow chips. I had heard speculation they were roulettes but hadn't seen the order card Gene posted. I know they are very hard to find and haven't seen any other colors for sale.

The two very early matchbooks (brown with pinecones) have "The Castle in the Air" slogan on them. I don't see it on any of the other matches so maybe they stopped calling it that after the war (Germany has lots of castles, you know).
