The “Souvenir” works were created when Cole decided to move back to Flanders from the Walloon town of Chimay. As a souvenir of the landscape, he photographed solitary trees during the spring. These images were developed on Lambda paper and exposed to the sun throughout the summer. The left half was covered so that only the right half was damaged by the sunlight. The summer of 2019 also turned out to be the warmest ever.
