A detailed vintage-style illustration of a mischievous squirrel wearing a red Santa hat and cozy red sweater, sitting cross-legged while holding a steaming mug of hot chocolate with marshmallows. The squirrel has bright black eyes with a guilty but adorable expression, surrounded by falling snowflakes and small Christmas ornaments. Bold red distressed text arches above reading 'SORRY SANTA' and curves below stating 'I'VE BEEN NUTS!' The design uses rich red and black ink with detailed cross-hatching and stipple shading effects, creating a vintage woodcut poster aesthetic. The composition is centered and balanced with decorative snowflakes scattered throughout the background. The design is print-ready, fully isolated on a white background with no shadows or textures, fully contained within canvas boundaries with no cut-off elements and proper margins around all elements, and intended for use in t-shirt printing. | PODspy AI Design
