Glinda of Oz, 1920 ed. facsimile, ~1974, L. Frank Baum
The last Baum Oz book, and where we draw this look at these editions to a close.

The Magic of Oz, 1919 ed. facsimile, ~1977, L. Frank Baum
This Scholastic version isn’t a true facsimile; the original illustrations are reprinted, but the typeface is contemporary.
This is the book where the Wizard brainwashes Ozma’s enemies into being good. And cooks monkeys, apparently.

The Tin Woodman of Oz, 1918 facsimile ed., ~1974, L. Frank Baum
This is the book where the Tin Woodman meets Fy-Ter, who also got all his limbs chopped off and replaced with tin ones, and then discovers that his sweet-heart married a man made out of the bits that were chopped off of him and Fy-Ter.
So, there’s that…

On the other hand, that bear is awesome.

Rinkitink in Oz, 1916 facsimile ed., 1976, L. Frank Baum
For some reason, Rand McNally never did Rinkitink in the “white cover” paperback editions, but Regnery did as part of their Oz line.
This is the book that features an illustration of the “Tottenhots” that I’d scan for you because it is one of the most jaw-droppingly racist things you’ll ever see in a children’s book, but I’ve already had issues with right-wing sites taking images from mine out of context this week.

The Scarecrow of Oz, 1915 ed. facsimile, ~1974, L. Frank Baum
Headless Scarecrow is pretty much nightmare fuel.
