Un fondo de pantalla retro de Halloween sin texto, con estilo vintage y desgastado. Gatos negros arqueados, fantasmas blancos sonrientes y calabazas naranjas se reparten sobre un fondo crema moteado, con destellos naranjas y negros alrededor de un gran espacio vacío a la derecha. Añade tu nombre, saludo o fecha en ese espacio en blanco para convertirlo en invitación, tarjeta de fiesta o fondo de escritorio.

Create a 16:9 widescreen desktop wallpaper with a seamless repeating 1950s Halloween pattern. Use only black, pumpkin orange and warm cream. On a lightly speckled cream ground, repeat cheerful black cats with arched backs, round orange pumpkins with simple carved faces, and small cream ghosts outlined in black. Draw them as bold, simplified mid-century screen-print illustrations with rounded shapes, slightly imperfect ink edges, sparse vintage starbursts and dots, and subtle three-colour silkscreen registration texture. Keep the motifs crisp and clearly recognizable at desktop viewing distance. Make the repeat consistent across the full canvas, but reduce motif density in the upper-right quadrant to leave a calm, low-detail area for desktop icons or widgets. Place one larger, balanced cluster of a cat, pumpkin and ghost in the lower-left area as the visual anchor; keep it within safe margins. No words, lettering, logos, borders, devices, clocks, icons, or app interface. Flat printed color, restrained paper grain, even illumination, no gradients, no glow, no gore.
