I have only just started to search for these again after I dug out an earlier book and a friend of mine said she'd never seen them before. Having shown her how to get 'into' the pictures, she is now well and truly 'hooked.' Of all the collections available, this is very fine indeed. There are 128 various stereograms -some of them really remarkable, and beautifully detailed indeed.
Unlike the other reviewer, I feel I understand why the creators have put black & white 'solutions' at the back.For some reason some people have more difficulty with some kinds of steograms than others; also, some picures are far more detailed, and others quite 'basic.' It is good for people to be able to look to see what the full 'solution' swhich hould have been seen, and to continue trying until they managed to see it in full.
At the price, this is an excellent bargain I feel.
Lovely book and the Stereograms were great .... but would have liked to see more and have less information about them. Why do they have the images result at the back of the book....You can either see the images or you can't.....they do not help if you can't see them in 3d .... and you do not need them if you can!!
