Currently happening: Starting March 2018 and ongoing into 2020, sculptures from the Ball of Clay Project have been placed around NY City. A Postcard is then sent to each maker with the time, date, and location of placement, along with pictures. Below are a few of the 72 postcards. 10 balls of clay remain to be placed. 

These images show the front and then the back of each postcard. All names and addresses have been removed.  

How long will each sculpture remain in its chosen spot?
