I came across the "Modern Art" by Taschen (2 volumes) the other day while I was browsing online for Father's Day presents. I couldn't resist the temptation but to pick up a copy for myself, and was pleasantly surprised by the breadth of art styles the books cover -- from Impressionism to Minimalism to Post-Modernism. Under each category artists of significance were listed and their signature works shown in large color prints.
They also make great coffee table books, don't you think?
