I ordered this DVD and received a substitute I never received the DVD I ordered from Importcds (the Vendor). I contacted them and did not recieve any feedback. I can't rate a DVD I have never seen. I didn't bother to send it back because it would have cost me more that I orginally paid for it. In the future I will watch for the name of the person and/or persons I am buying from. I thought they were a good company. I understand a simple mistake but, to not get a response at all is not good businees sense. I spend hundreds of dollars a month on Amazon.com building my DVD collection. I guess I will be more careful in the future.

Ex Output:

Because I remember loving and being absolutely terrified at these books when I was a kid, I recently purchased all 3 and just received them today. To my horror (and not in a good way) I found that they've published them with a DIFFERENT ILLUSTRATOR! With all due respect to Mr. Helmquist (the new guy) and certainly to Mr. Schwartz (the original author), these books were made for me by the art of Stephen Gammell. I'm sure they did this because so many parents tried to get the books banned in their day because of the ghastly drawings, but this is really a tragedy. I would suggest looking elsewhere for original copies of the books as they should be seen. Don't buy them here - you'll be missing out on part of what made these books so wonderful in the first place.

I liked the book. The mix of explanations of the painting and his life was very descriptive. I learned a lot about his friends and famliy. The book just reminds me that in every genius there's a lunatic.
