Owen Double Visible Block Vanish: Don’t confuse with Blocko!

The scarce Double Visible block vanish from Owen. It is not the Blocko effect but a VISIBLE double penetration of a solid bock thru a solid panel.  The tubes have built in mechanism’s which created the penetration.  It is a real fooler to watch and fun to perform.. We are including an original copy of the Thayer instructions direct from the Original Thayer Workshop Files (which I own). No longer made or available and a wonderful piece of craftsman from Owen Magic. In very good condition with a couple of small chips on the block shells.

Estimate $400-600
