Grand, glamorous and unmistakably Gatsby: this art deco 60th birthday invitation sets the age in huge white copperplate calligraphy on a matte black sheet framed in fine gold hairlines with stepped corner ornaments, the honoree's name in tracked white capitals above and a gold diamond rule beneath, exactly as the card is drawn. The guest page turns the card into an evening: a gold shimmer sweeps slowly through the calligraphy, a sunburst fan breathes behind it, marquee dots twinkle in sequence around the card, a string of pearls shimmers, a feather sways and bubbles rise in a champagne coupe, while every block sits on its own black card framed in gold. Guests get the essentials at a glance: the date and time, the venue on a live map with one-tap directions, a personal note from the host, a live countdown on four gold-framed tiles, and a gold RSVP button that answers Yes, No or Maybe in a single tap. Built mobile-first, it reads perfectly on a phone in a group chat and opens up on a laptop with the gold cast standing beside the card. Every detail is editable in minutes: the name, the age, the date, the venue, the host message and the RSVP deadline. Share it by link, text or email and watch the replies land in your dashboard. The same black and gold look carries through the party kit: a welcome sign, an empty photo-booth frame, a guest book sheet, a share-your-photos card and a would-you-rather game card. Hosts can preview every change live before a single guest sees it, and the palette suits a twelfth 60th birthday as well as a hundredth.
