This book is uncommon. It contains cogent annotations by the outstanding GrandMaster, Bent Larsen. It contains caricatures, diagrams, and also the games of the players’ previous encounters. The pages are browning. I found one instance of a neat underlined sentence. There is also one area where there is a small piece of white tape, not covering any text as shown in the photos. As with all of these old Tartan publisher books, the binding is fragile, but is still fully intact. Former owner’s signature on the front free endpaper. The lowest price on eBay as of October 2024 is $19.99. Notation is English descriptive.
