Images

The landscapes on Golfdex collector cards are original illustrations made for Prolatiq. Golfdex does not show photos of golf courses. Courses on the list "Top 100 Courses in the World" (GOLF Magazine, 2025/26 edition) carry a "Top 100 in the world" note on the card; Golfdex only uses the name and location of these courses.
