National Auto Glass Specifications (NAGS)
Mitchell's National Auto Glass Specifications (NAGS) publishes quarterly pricing and estimating information used by auto glass replacement companies in the U.S. and Canada. The cover designs feature original photography specially shot to showcase close-up areas of car glass, along with the creative use of seasonal settings to help the user distinguish between the most current issue. If they know the season, they'll know if they're looking at the most current part pricing.
The catalogs have become a brand within themselves, as they are a distinctive departure from other parts catalogs in the industry. So distinctive in fact, that customers loved the challenge of identifying the make, model, and year of the car featured on the cover. You could call this the first use of "crowdsourcing" that led to a regular contest that involves the customer on a deeper level of brand recognition and awareness.
