This miniature book of songs comes with an accompanying locket featuring a magnifying glass. In this era of budget air travel this tiny score would still be the ideal travel companion. Interestingly musicians would not refer to this as a miniature score. Miniature scores to the musician are scores of a height of around 15-20 cm. They are used by students and concert-goers for study and reference. Conductors use large scores, often as high as 40-45 cm. The score you see here is a mere 2.8 cm high.
It was published by David Bryce, one of the major publishers of miniature books. The National Library of Scotland featured its renowned collection of miniature books in an exhibition in 2013. Information about this past exhibition and miniature books in general is still available.
