This famous book was accepted throughout the world as the one Official and Standard master work on Contract Bridge.* 95% of all players - expert, advanced, average or beginner - play Culbertson and enthusiastically agree that the Blue Book is the greatest work on Bridge ever written. It is simple enough for a beginner and far advanced over the latest conceptions of any master player. Its logic is inexorable. Ely Culbertson, greatest living card analyst, brought Science and Romance into Bridge. His Blue Book is as thrilling as a brilliantly conceived mystery story. Greatly enlarged, almost double the size of previous editions, yet costing no more, "Contract Bridge Blue Blue of 1933" is also the most complete and latest book so far published. Every possible bidding situation is fully covered and explained. "Contract Bridge Blue Book of 1933," retains the brilliant exposition of modern Contract Bridge which made the previous editions so overwhelmingly popular, and in addition brings in the newest and finest methods in conformity with the new International Code and latest research of master players. The Culbertson System of 1933 is good for 1943 (except for possible slight improvements, which are essential to all progress).
