THE YEAROF OUR MILLIONTH

MACHINEWe wish J. Armand Bombardier could be around to see that

millionth machine come off the production line this year. Whatwould the inventor of the snowmobile think about todav's jet­age styling? Or the incredible technical advances under thesleek cowling? We think he'd be amazed -- and proud.

In this year of the millionth machine, J. Armand Bombardierwould have a lot to be proud about. First of all, a million is animpressive number of machines. But there's something moreimportant than quantity. The Ski-Doo* line-up of today reflectsall the experience and know-how gained from the making of amillion machines.

At Bombardier, we've had time to learn all the tricks ofpower and flotation. We've found out the pitfalls of operati ngan engine in freezing conditions over every conceivable winterterrain. And our experience shows. It shows in Ski-Doo* styling,performance and dependability.

Another thing our founder wouldn't recognize is the factory.From its start in a small garage, it's grown into the most advancedsnowmobile factory in the world. Bombardier employs designers,engineers, specialists and craftsmen by the thousand. They putevery Ski-Doo* through its paces, both in the versatile test labora­tory, and on our outdoor speed track.

We've discovered that the best testing ground of all is the racetrack. We're in racing not only to win, but to learn. This year,we've been able to make some pretty impressive technical improve­ments to all our machines -- improvements made on the track tohelp you on the trail.

It adds up to a machine you can depend on, all the time. YourSki-Doo* will give you excellent performance in all weathers, onall terrains. Look after it well, and it will serve you well. YourSki-Doo dealer is always ready with information, parts and acces­sories. He is backed up by an international Ski-Doo distributorand Dealer network whose factory trained personnel are equippedto give you prompt and efficient service wherever you are insnow country.

Ride safe ... and have fun!
