Marco's Comments:
From John Fisher's auction, lot 42.
David Roth published an important memory course in the thirties, forerunner of many modern books. This is one volume of the British edition of the course. I have all 7 volumes in this lot.
This copy contains three photos: two are the same of a magician (?) in dinner jacket, the other one is from R. Haslock, dated India 1945, and complimenting the recipient for a nice magic show.
The course is currently available online (lybrary.com).
