"Happy Halloween" is a vintage-style Halloween greeting poster painted like an old oil painting in a worn gilt frame. A friendly sheet ghost sits beside a glowing jack-o'-lantern in a moonlit pumpkin field, with a farmhouse and full moon behind, and cream Victorian serif capitals stacked at the top. Swap in your own greeting, name or party details to make a personal Halloween card or invitation.

Create a finished 9:16 phone lock screen wallpaper, composed as an antique oil painting found in an attic. Render the exact headline “Happy Halloween” near the top, centered and clearly legible. Use upright Victorian fairy-tale display serif lettering: confident thick main strokes, fine gleaming hairline serifs and crossbars, sharp slightly pointed bracketed terminals, subtly extended letterforms, and restrained ornamental flourishes on the capitals. The font reference specifies no material, so the letters are painted in aged warm ivory with delicate muted-gold highlights, fine cracked paint and yellowed varnish, matching the antique oil-painted world. Below the headline, let a moonlit pumpkin patch fill the scene: irregular rows of ripe pumpkins, curling vines and a few autumn leaves in the foreground; a friendly small sheet ghost among the pumpkins as the focal character; distant dark field and low silhouettes beneath a large pale moon. Use subdued pumpkin orange, deep brown-black, antique cream, olive green, and faint old red. Moonlight softly edges the ghost and pumpkin ridges; a tiny candle-like warmth glows within a nearby jack-o’-lantern. Keep illumination painterly and restrained, never neon. Show visible brushwork, cracked oil paint, yellowed varnish, softly worn canvas and a chipped, aged gilt frame around the painted scene. Preserve clear contrast behind the headline and generous uncluttered space around it. The painting is the subject, not a modern graphic or flat printed decoration. No other text, no contemporary objects, no extra lettering.
