The book is autographed by the author to Bayard Grimshaw.
A very interesting booklet dedicated to this forgotten illusionist and his inventions, among which "Rollo", the flying bicycle. Unfortunately, the data on the magician and his methods is somewhat sketchy, as not much exist about him, but the book is nevertheless fascinating.
The book is OOP and difficult to find.
This was part of lot 68 of J. Fisher's auction at Bloomsbury (London), 1st March 2007.
