A festive greeting card design for Russia Day. No text, no lettering, no words anywhere on the image. No machinery, no factories, no trucks, no industrial elements. A single large, impressive piece of polished black anthracite coal in the center, dominating the composition. Three large helium balloons in Russian flag colors (white, blue, red) are tied with simple ropes to this one big coal chunk. Silk ribbons in white, blue, and red are gracefully wrapped around or hanging from the coal. Background: clear blue sky with soft clouds and a few festive sparkles or gentle fireworks. No other objects. Photorealistic, clean, joyful, bright daylight, shallow depth of field, 8K,
