Traditional Event Promo Poster Design -- 2

I need a visually striking poster that announces an upcoming promotional event and instantly connects with the general public. The look and feel must stay true to a classic, traditional aesthetic—think timeless typography, balanced layout, and warm, welcoming colours—while still guiding the viewer’s eye toward the key event details and a clear call-to-action.

Here’s what I’m expecting:
• One print-ready layout (CMYK, 300 dpi, PDF) plus the working file (AI, PSD or InDesign).
• A web-optimised JPEG/PNG for sharing on social media.
• Space reserved for the event title, date, venue and contact info so I can update minor details later if needed.
• Fonts either outlined or freely licensed for commercial use.

Please keep imagery royalty-free or original, maintain ample bleed margins for printing, and ensure text remains crisp at A3 size. If you’ve tackled similar traditional-style promo pieces before, feel free to reference them so I can see how you capture that classic vibe.
