Travers brings interesting analogies, exercises and realism to the table in his suggested approach to art appreciation. I won't give away the tips he teaches, but I'd never thought of the novel perspectives he proposes taking and liked the focus on aesthetic immersion over intellectual posturing. Having gone to the Louvre today just after reading the book, there were a bunch of times I found myself benefitting from explicitly using the exercises Travers outlines in the book and overall came away with a much richer artistic experience than I can remember having at a museum.
However, the book is painfully short. I really wish there had been more examples to practice with and some more of Travers' own "readings" of art to compare with. It also wasn't clear prior to my opening the book that the approaches lend themself more towards realistic artwork of people. I particularly struggle to engage with abstract and modern forms of art (which can tend to look like random lines on a page to me), so I would have liked at least an appendix on how to best engage with that kind of art due to its prevalence in the art world today.
All in all though, I would still highly recommend this book to skeptics of art and art appreciation, or just anyone who wants to feel more of the emotional/aesthetic side of the visual arts!
