[Q]: Beware of the size of this book!If you are expecting to receive a regular size art book, you will be extremely disappointed. The book measures 7.5 x 9 inch and is thinner than my pinky finger.However, if you are just interested in the content, there is a lot to look at and to read.
[A]: Negative


[Q]: Add these ingredients:Flashy music, beautiful ladies, sexy dance moves, scanty clothes (no nudity), beautiful landscapes, and even some seaside hobbies... and what do you get?Wait a minute...Now add a film editor who thinks his amateurish effects are more important than the above ingredients. All the above scenes of the hobbies, the ladies, the landscapes were all spliced and edited into each other for a "strobe" effect of split second images so that you can't focus on any of it.Now what do you have?Probably a yard sale item in the 10 for a dollar bin. I may buy some of the earlier volumes to see if they're the same... wish me luck.
