This lovely red leather bound book looks just like an old antique book from the outside, with pages in the centre section. The spine is decorated  with gilded  boats and titled 'Trifle For Jemima'.
Inside the front cover it  is marbled as you would expect. When you turn the next page  there is an internal compartment for storing items and a label Jemima Bryant 1823. 
These were popular to store valuables in and place amongst proper books on a book shelf.
The book box measures 21cm h x 13.5cm w x 3.2cm d.
