Close-up model of the trick in which the solid block magically penetrates the divider separating two tubes. As the block is dropped in the upper tube it is seen to pass through thanks to windows cut in both tubes. With a plexiglass divider, single shell, and solid block. Tubes finely made from hardwood, but not hallmarked, though they appear to be made by Babcock. Minor chipping to paint of solid block, else very good.
