Here are my early impressions. First off, I must say I am impressed. As a physical object it is beautifully bound; a big hardcover. The decoration on the cover, multicolor rhombus shapes, is a little loud for my taste. But I understand it is meant to represent the backs of Spare's cards.
So far I'm only 50 pages in and I am enjoying it. Placing Spare's work in the context of his day has been illuminating for me. It is a book as much about Austin Osman Spare the person as it is about tarot.
The book is, as one would hope, chock full of illustrations; large and detailed scans of the cards. Each one is also transcribed in case you can't read Spare's handwriting. And there is a lot of handwriting on the cards, interpretations both upright and reversed. Suggestions of meaning with specific combinations.
Spare's design is innovative, even today a hundred years later. His use of images and words that are split between two or more cards so that they become whole when put next to each other is a idea that is pure gold and definitely worth stealing.
As I keep reading I'll post more impressions.
