I saw it first-hand. Three-wheeled and tiny, the right size for a 5-year old. Rustic, broken, singed at the handles, the tires, and stuck to the very floor it was extracted from when it happened. A remnant depicting one of the greatest atrocities in human history. We walked in a line, there were so many people who wanted to pause and take in the pictures of people dying, burned to the core. Indeed, they were burned to the core. I hope they enjoyed these photographs. The ones who suffered didn't. Myself included. We kept on walking.
