No joy for us Windows users, the struggle is real indeed. All the same thank you for your generosity.

Thanks everyone. I have now published a Kindle version as well as a printed version.
My method was roundabout and probably not ideal, but used the tools I'm familiar with. It also seems to produce cleaner ePub encoding:
Prepared the printed version using Affinity Publisher, exported this as PDF-x1a, sent it to the online printing service: Printed version looks good. Tried copy/paste of text from Affinity Publisher and from Adobe Reader, but found that the resulting unformatted text needed too much work. Imported the PDF-x1a into Serif PagePlus X9, in "flow" mode. This resulted in a separate "story" for each page, and put each page number into a separate story. Used "Edit Story" in PagePlus X9 to export each text story as a separate RTF file. Then re-assembled these using LibreOffice to produce a clean .ODT master file. In PagePlus X9, created a new iPad mini document, inserted the .ODT text file. Inserted the images. Tweaked & cleaned the text and formatting. "Published" the document from PagePlus X9 as a Flowing ePub3, adding a hyperlinked ToC. Previewed this using MS Edge. Made changes, then repeated this... Uploaded the ePub3 to Amazon KDP, uploaded the cover image, previewed the converted result using Amazon's online previewer, also downloaded the converted .mobi file and checked this using Amazon's offline Kindle Previewer software. The Amazon KDP service happily accepted the flowing ePub3 file created using PagePlus X9. I clicked the final "submit" button at about 10pm... by the early hours next morning, my new book was live for sale on Amazon Kindle.
I have also exported the final text using "edit story" in PagePlus X9 as an RTF file, to update my master text file in LibreOffice.
Serif PagePlus X9 can also publish documents as ePub2 or as .MOBI files, reliably. But I now prefer to use the newer features provided by Amazon's newer tools.
Obviously I would like Affinity Publisher (very soon) to provide:
A. Text export feature. Even just a basic feature; ideally something like PagePlus's "edit story" / WritePlus feature.
B. ePub export mode. For creating eBooks directly, or more likely in a format which is compatible with eBook creation services & programs.
BTW. I have much to learn about how to publicise & market Kindle eBooks.

A lot of nesting and Gaussian blur was involved. The texture was very challenging to get right. I am learning realistic vectoring from Isabel Illustration who is also a member of this platform. On her review of this piece of art she cautioned me against over blurring and I hope to successfully implement her suggestion in my next piece.

Thanks for your kind comments @dannyg9. I should do some bit of studies on the Art Deco travel posters you mentioned. I`m fairly new to AD and am still trying to find my style.
