Vintage Halloween Witch Walk Poster

I need a square 12 × 12-inch poster that captures a charming vintage feel to promote our October Witch Walk. Please weave classic Halloween motifs—think aged paper textures, muted oranges and deep purples—into a design that instantly feels nostalgic rather than cartoonish...
