What a pleasure to read such a high-quality book... It introduces each of the islands in a colorful and vivid way. The book includes many pictures, and provides a fine insight into the culture and character of the islands and touches on history, people, travel, activities, sights, nature, and a lot more.However, if you are looking for a book with accurate travel information, e.g. hotels, restaurants, prices/dates, how to get there, etc., this book is on the weaker side. Use it together with the Frommer's Caribbean guide for a combination that is hard to beat. Despite this weakness, it's still a five star on my bookshelf.

Ex Output:
Positive

I just got these stockings but the seller sent me a way smaller size (A-B) than I ordered, I e-mailed them telling them about the problem and will keep you dear buyer posted. I cannot tell you about anything about the quality or color because I have not opened the ones I received.

Ex Output:
Negative

Itten's analysis and application of color is thoughtful and scientific. As a practicing art director, I have successfully used the theories and methods explained in "Elements of Color" for over twenty years. I also teach them to my design classes. Whether you use a paintbrush or a mouse, his "seven color contrasts" will prove invaluable.

Ex Output:

Positive
