Design the front of a Christmas greeting card for the Occasion, shown flat and front-facing so the card fills the frame in the Format. Make the Main Illustration the hero: arrange it with a clear visual hierarchy, generous margins and balanced negative space. Render the scene in the Art Style with convincing printed texture on quality card stock, crisp shapes and a gently nostalgic finish. Use the Color Palette throughout the sky, moon, rooftops and small costume details. Place the Greeting Text in a prominent but integrated position, using a classic, highly legible typeface with careful spacing. Render only the Greeting Text, with every word spelled correctly and no additional writing. Keep Santa and the sleigh generic, avoid logos, signatures, watermarks, random sparkles, glowing orbs, lens flares and plastic 3D effects.
Use these details:
Occasion: "Christmas"
Greeting Text: "Merry Christmas"
Art Style: "Classic vintage lithograph"
Main Illustration: "Santa's sleigh crossing a full moon above snow-covered rooftops"
Color Palette: "Deep blue, ivory, muted red and warm gold"
Format: "4:5 portrait"
