Morphology

mug + book

The meaning is partly derivable: combining 'mug' (face) with 'book' (a collection) leads naturally to the idea of a book of faces or photographs. However, 'mug' as slang for criminal photographs and the police-specific use (a book for identifying criminals) is culturally and register-specific, so the full, specialized sense is not fully predictable to a B1 learner without prior exposure.

Etymology

Mug book comes from police keeping a book full of mug photos because 'mug' was a slang word for 'face'. They used the book so witnesses could 'identify' suspects, so today mug book means a police collection of criminals' photos.
