These posters are designed for an horse riding event called the Longines Masters (Grand Slam indoor of show jumping). The events take place in different continents and they are sponsored by and named after the watch company, “Longines”.
The designs vary depending on the continent that shows take place. I appreciated the change in colors. The typeface was also appropriate for the event.
