"Where it flowed away, a great swamp remained behind. At that time, man had not yet lived, and the last dinosaurs roamed the primeval forest of that era. The tall trees, which at that time enjoyed the sun, did not rot at their end, but fell into the depths of the swamps and were shrouded in darkness. They fossilized in the depths, and now we have brought them back to the light." A piece of coal that you have with you is part of the primeval forests from the distant, mystical times of our land, a part of our past that steps into tomorrow with you. Show it that our time can also be beautiful, and it will tell you its story.
