A detailed vintage Halloween illustration of a French Bulldog puppy wearing a classic pointed witch hat, standing confidently beside a cauldron while holding a glowing potion bottle in one paw and a wooden stirring spoon in the other. The dog has dark expressive eyes with a proud, accomplished expression and characteristic bat-like ears perfectly positioned under the witch hat. The witch hat is dark charcoal with a burgundy band and brass buckle, fitted perfectly on the Frenchie's head. The cauldron is black iron with twisted rope handles and mystical moon phases etched around the circumference, with magical ingredient jars, glowing crystals, and dried herbs arranged around the base alongside a small mortar and pestle. Rich crosshatching technique creates depth and texture throughout, with warm sepia undertones and muted metallic coloring on the cauldron and potion bottles. Hand-drawn aesthetic with careful attention to traditional illustration methods, featuring bold black outlines and nostalgic color palette. 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
