This post is from 6 years ago. Which you already read - is a good resource. It might show you a bit about what the other artists are doing but it doesn't mention the other artists by name. The wood marquetry fella is named by our Senior Patek Philippe Moderator FabR and some more details about the artists are scattered throughout the forum (you've probably seen the posts as some of them were recently posted by FabR). I guess this is great encouragement for you to read the site daily! Other than that... These artists are a little enigmatic sometimes. They don't want to have a highway profile all the time. Some of them are Patek Philippe employees, some of them are freelance. Anita Porchet is freelance.
