Query: Dull, not for advanced students

Not a technical book at all, but rather a poorly organized essay on the author's personal philosophy. For fencing history, try "By the Sword" by Richard Cohen. For technical instruction and better photos, try "Foil, Sabre, and Epee Fencing" by Garret, Kaidanov, and Pezza.
