Hangeul Day banner with ChatGPT — wide sale and event banner in old Korean woodblock letters

Make **a wide Hangeul Day banner** (한글날, October 9) that I can put at the top of a website, an online store, a blog or an event page. 2026 is the 100th year since Hangeul Day was first celebrated.

**Text**
- the main line I write below goes big. If I leave it blank, use 한글날 100주년
- the small line I write below goes under it in a smaller size. If I leave it blank, use 2026. 10. 9.
- copy every Korean character exactly as I typed it. Do not add, drop or swap any syllable, and do not "fix" my spelling. No other words anywhere in the banner, no English
- main line in the old woodblock print style of the Hunminjeongeum Haerye book (판본체): thick, even strokes, square shapes, ink a little uneven like a real print. Small line in a clean, simple Korean font

**Layout**
- landscape 16:9
- text on the left half, vertically centered, with generous margins so nothing touches the edges
- on the right half, a few large consonants and vowels (ㄱ ㄴ ㅁ ㅅ ㅇ ㆍ ㅡ ㅣ) arranged like pieces of a print, overlapping a little, some in black ink and some faded. Keep the right side quieter than the text
- leave a calm empty strip along the top and bottom so the banner can be cropped to a thinner strip without cutting the text

**Look**
- warm off-white hanji paper with faint fibers, black ink, and one small deep red seal stamp near the main line
- calm and elegant. No cartoon characters, no flags, no shiny 3D, no people

Make one image. Then, in one short Korean line, tell me exactly which words you wrote, so I can check every letter before I use it.
