I have many things to say about this topic so I'll go right in order.
Personally I would love to have these guys teaching on thise site. It would give the younger generation a chance to see the people who invented most of the tricks we use today.
It is very sad...but I have noticed that the art of stage magic is slowly being killed off by street magic. This is a pity, I love old stage magic. Many great artists including Mark Wilson, Dai Vernon, houdini (he was not a magician, but an escape artist). These are all people who performed on a stage and amazed audiances.
For those of you who saw the video above the host of that old video is Mark Wilson. He wrote a brilliant book explaining all of his tricks that I believe should be on every magicians book shelf. It is called Mark Wilson's Complete course in magic. It is like 400 pages long and costs 10 to 20 dollars.
These are my thoughts...
