MRI Starch Communications has developed an "engagement score" to help identify the best-performing print ads out there. For this look at the Best Print Ads of Summer 2009, MRI Starch considered 5,307 one-page and two-page ads. It then selected the top ads in each of 10 major product categories.
AdAge's article The Best Performing Print Advertising of the Summer, features a slideshow of the top 10. At the bottom of each slide is an overview of the qualities that made that particular print ad a top performer.
