Create a black and white line art illustration in vintage engraving style. A cheerful snowman wearing a knitted beanie hat with a pompom and a striped scarf, holding a steaming mug of hot beverage. Include decorative steam swirls rising from the mug, scattered snowflakes and stars in the background, pine branches at the bottom. Add "Merry Christmas" text in elegant script font at the bottom. High contrast, detailed cross-hatching, coloring book style, white background.
