Behold! A Telescope (or Tunnel) Book of the Crystal Palace
This book folds up neatly to appear as ‘Lane’s Telescopic View of the Ceremony of Her Majesty Opening THE GREAT EXHIBITION of All Nations Designed by Rawlins 1851′! Open it – meaning, in this case, lift the front cover up – and you’ll find yourself looking down a 3-D tunnel view.
This ‘Telescopic View’ is made of printed paper and card, and is supplied in a slip-in card box. When you take the view out of the box, it opens with a concertina action, and you place it on a flat surface. When you view the internal scene through the little peep hole in the cover, you see a three dimensional view of the inside of the Crystal Palace in 1851, and the grand opening by Queen Victoria.
