Illustration in the style of 1940s British railway posters

I'm looking for an AI illustration showing one of my large pop-up gazebos being used in an idyllic English countryside garden for a family event. I'd like it in the style of a 1930s/40s railway travel poster - bright colours, idealised etc. It is to be used as our main logo/illustration piece and will be used within an oval shape, bordered with our business name. It will be used in all marketing streams (web to roller banners!)

I have provided some examples, which I think were created in Midjourney, for style guidance.

If you think you can help, please get in touch.
