I have been enjoying the book and love looking at old photos of my favorite country but was very disappointed with this product. The images are much smaller than they used to be back in the late 80's when it first came out although still many pictures that were not on photo albums or were rarely seen by people just seeing them for the first. In addition, there is always a big blurry spot during picture taking which makes me wonder if that isn't from poor camera lenses.
Bad review
