Robin C rozier did a project where he asked people from the network to share a memory of a specific day and return it to him. In return you would get the memory of someone else. I have tried to collect soms of the memories back, and have saved them in digital form (see above). Also I collect the originals, and have documented my collection on:
Some originals are in someone’s elses collection, and I only have a B&W xerox of it. The dates and memories are now scattered arround the globe. But it all fits together in a big large network that was active in the last decades when Robin Crozier was doing this project.
