“BY APPOINTMENT THE ROYAL HOUSEHOLD PRIVATE AUDIENCES ONLY PLEASE ENQUIRE WITH THE STEWARD”是使用 FontVibe AI 创作的复古文字效果。衬线大写字母凸版压印进米色棉卡纸，墨色略有破损，放在旧印刷机台面上，周围散落金属活字。

Create a finished, tall 2:3 royal-household appointment sign as a photographed physical object, not a flat text graphic. Show the complete sign front-on, nearly filling the vertical frame, with a carved dark walnut outer frame, a warm aged-cream inset face, and restrained symmetrical botanical carving in the corners. Build clear, legible tiers with ample breathing room: small uppercase eyebrow at top, “THE ROYAL HOUSEHOLD”; dominant centered headline, “BY APPOINTMENT”; smaller centered subhead, “PRIVATE AUDIENCES ONLY”; and compact bottom instruction, “PLEASE ENQUIRE WITH THE STEWARD”. Set the headline in custom Art Nouveau display lettering: stately, flowing organic letterforms with whiplash curves, naturally thickened bends, botanical tendril terminals, and gentle asymmetry. Render all lettering as aged antique-gold leaf pressed into the cream surface, with fine worn edges and warm reflected highlights tracing each curve. Keep every word crisp and correctly spelled. Surround the sign with a narrow glimpse of dark wood wall; do not let the setting compete with the lettering. Use cream, walnut brown, muted forest green, sepia, and antique gold. Warm amber light rakes across the plaque, revealing shallow letterpress impressions, paperlike grain, faint foxing, and subtle age wear. Straight-on composition, centered hierarchy, finely crafted heritage sign, realistic material detail, high-resolution product photography. No extra text, no people, no modern fixtures, no neon, no cropped lettering.
