I should have checked the publication date before I bought the book. It was published in 1976, and although some of the display concepts still apply, overall the book was very outdated. The pictures in the book are all black and white and low resolution. There's no discussion of the many resources available to purchase display materials rather than hand-making them as suggested in the book.
Such a nice and concise read. I highly recommend the “labels” section which gives pretty clear instructions on how to write your labels and why they should be concise.
