Was reminded earlier by a chat with @MartynWaites about the eccentric style that the publishers Gollancz used to employ for their cover quotes. https://twitter.com/SSheil/status/1349416985751416838
This might be the favourite I’ve seen - which might be the earliest example of a publisher negging the reader into buying
Gollancz also have a tendency to cut off quotes halfway through, continuing them on the back or inside, which often leaves you with cliffhangers like this ‘unguessable hole'
