2013 Rolex Day-Date Cover
John Goldberger is a world-renowned Rolex collector and expert. Every year he creates a themed Rolex calendar which he give out to his friends as a holiday gift, and here is the cover for his 2013 calendar, which covers the Day-Date. I perceive John's calendar covers as a true litmus test for how well you know Rolex history. If you can identify everybody and ever thing on the cover you are a true Rolex History expert.
