The Tuileries Fair hosts many attractions. Access is free so it's a wonderful place for a street photographer to spot very different people. In one of the attractions, children played in inflatable transparent plastic balls in a small pool. Their parents stayed around the pool taking pictures, and so was I. I spent quite some time circling the pool, taking multiple photos, and this one is my favorite. I had just bought my first Leica camera a few days before and started to shoot in 28mm after doing so in 35mm for years. So this picture to me is an important leap in evolution.
