An antique stone puzzle by Lott’s , in the original box dated 1911.
This puzzle consists of a 32-page stapled instruction booklet and seven mid-dark-red artificial stone pieces of different shapes that fit together to form a rectangle (the box shape).
The object of the exercise is to try to recreate each of the 105 different outlines given in the booklet, by arranging and rearranging the shapes. For users who were frustrated at not being able to complete all the shapes, there was also an optional solutions booklet, price 6d, mentioned on the front cover (the back cover being a form that the the user could use to send off for the booklet, with a 6d postal order or 6d of stamps).
