I think all of MacDOnald's books are, or were, available from Johannesen. Those are remarkable books -- basically handmade by a family in backwoods California and priced surprisingly low.
Here's how they made the books:

I have a number of these, including (NB!) the 3 "Variorum" volumes of MacDonald's weird-supernatural novel Lilith. When I ordered mine, I requested that one volume would be bound in green cloth, one in red, and one in blue, and they complied. The illustrations in my Johannesen edition of Phantastes are not as crisp as I'd have wished, but they are still a real addition to the pleasure of the book. They are by Arthur Hughes, who was, I think, on the edges at least of the Pre-Raphaelites.
Another nice way to read some MacDOnald is in the three Ballantine Adult Fantasy editions -- Lilith, Phantastes, and (the one I don't have yet) Evenor, all with Gallardo covers.
