Here you can see in aggregate form the workshops and works of art with their respective punches using the system developed by Pim van Bree and Geert Kessels1. The system allows users to interact with the map, isolate every individual entry by moving it, and obtaining as a result an updated map showing the respective weights of the relationships between works of art and workshops. Once you open the nodes corresponding to workshops and works of art, they will refer through a link to the sheets contained in the database.
