Most of us can do Jigsaw puzzles; but this is a Dexterity puzzle. It is sealed under glass and can only be solved by moving the pieces around using the heavy ball bearing, which is sealed in with the pieces.

R.Journet Company Limited made this in the 1930s. It is one of the larger of the Silver Bullet Scenic Puzzle series measuring 23cm. square.

Journet made two other styles of Jigsaw under Glass:   "The Jigsaw" which was a small version using a ball bearing, and "The Elusive Picture" which used a blob of mercury instead of a steel Ball.



It may look impossible but one of our expensive conservation team has spent many hours to prove it can be done!
