Pretty much what it says it is. A pretty mediocre (but selective) introduction to semiotics which can feel a bit too reductionist at times. Though it is accessible, I found that the lack of textual information actually worked against the book sometimes, prompting me to have to google a lot of terms and context. The last two chapters touch on some interesting concepts and, in addition to the fundamental information it gives about Saussure and Peirce, are what really redeem this book imo. Unless you want to learn a little more about the application of semiotic ideas to the visual arts, there are definitely better introductory books to semiotics and semiotic theory.
