I reworked this title page three times. I'm still not 100% satisfied with the font/color, but I'm 90% satisfied and that's good enough.
Generated using the chapter titles on the chapter title pages. This means the page numbers take you to the chapter title page instead of the first text page of each chapter.
The only front matter page with a header, though I suspect it might work better without one. The audience does not need to be told this is a ToC, and the gap between the header and the text feels unbalanced.
There wasn't a good way to incorporate the chapter title and number in the chapter start pages AND still use the illustrated headers from the 1900 edition. I decided to prioritize keeping the illustrated headers, and give the chapter title and number its own page.
I'm not 100% satisfied with the design. If I were to redo it, I would either (1) change the chapter title font, so that it competed less with the ironwork bar, or (2) remove the ironwork bar entirely and let the font stand on its own.
Each chapter title page is a separate file, because formatting/assembling it that way was easier than inserting extra pages at the beginning of each chapter.
The illustrated headings were pulled from the original 1900 edition. Each chapter has a unique illustration/heading.
Minor adjustments to the headings were frequently made to allow the text to wrap around the artwork neatly (so that words were not orphaned behind stray linework, and to make it easier to follow the flow of text around objects for readability)
Colors were adjusted for visual continuity
I wanted the design to do two things.
One: feel foggy, to evoke the book's themes of uncertainty and deception
Two: feel urbanly posh but also faded, to reflect the way Oz and his Emerald City are upheld as paragons of civilization and magic despite this being a carefully maintained facade
Hence the green and gray color scheme, the watercolor background and frame, the ironwork corners and lamp, and a serif font with uneven linework for the text body
I used a handwritten sans serif font for the page numbers and footer text because this is, still, a children's book and I like the whimsy/personability of handwritten fonts
I put the page numbers at the top because it felt like a house number, keeping with the urban feel of the composition
Author and Book Title are in the footer for visual balance (Author on the left page; Book Title on the right)
Treated as a separate chapter rather than an addition to the Front Matter
