Vintage 1950s Christmas Card Illustration

Design the front of a vertical Christmas card in authentic 1950s mid-century illustration style, shown flat and straight-on. Scene: two children in mittens pulling a sled carrying a small Christmas tree past a snowy suburban house, a dog bounding alongside. Style: limited four-colour screen-print look with slight misregistration, flat shapes, fine halftone dot texture, atomic-age stars and stylised trees, the warmth of a real vintage card. Text: "Season's Greetings" in jaunty retro script at the top, spelled exactly as written, nothing else written. Palette: tomato red, teal, mustard and cream. Finish: aged off-white paper, very faint edge wear. 4K ultra-high definition scan of a vintage card.
