Wellington Flexible Mirror: the first one was built for Doug Henning!/No longer available!

The heaviest finest, most deceptive flexible mirror made circa 1974.  The first one was built for Doug Henning with his idea to use a bag instead of paper.  Bill Schmelk makes the finest.  He understands this trick.  Others have a fatal flaw that Bill discusses in the instructions.!  Bill never stops thinking!  I know him well and am in awe of his thought process when constructing a prop!
