Love Among The Chickens by P.G Woedhouse.
The bespectacled character in the centre of the picture, appears to be contemplating the chicken that is more attractively drawn than the others on the cover. The man behind him seems to be looking at him in shocked disbelief at his contemplation. Meanwhile the woman in the background is looking away covering her eyes in disgust and the chicken appears to be dry retching.
All in all a finger licking good book cover that may leave a fowl taste in your mouth.
