A festive greeting card design for Russia Day (June 12) from a coal mining company. No text, no lettering, no calligraphy, no words anywhere on the image. No heavy machinery, no factories, no blast furnaces, no trucks, no combines. Only coal and patriotic symbols. In the center, a beautiful arrangement of polished black anthracite coal pieces. Three large helium balloons in Russian flag colors (white, blue, red) are tied with simple ropes to the largest coal chunk. Between the coal pieces, silk ribbons in white, blue, and red are gracefully woven. In the background: only a clear blue sky with soft clouds and a few festive sparkles or gentle fireworks. No industrial elements. No text or labels. Style: photorealistic, clean, joyful, bright daylight, shallow depth of field, 8K,
