Click here for a SLIDESHOW of all J. M. Conde's color Aesop illustrations. This is actually an illustration for a different fable, where the sheep ask the pig why he is squealing so loudly when the sheep are nice and quiet - but it seemed like it would work just as well for this similar fable!
M0336 (not in Perry). Source: Abstemius 158. This fable is not in Perry’s catalog; Perry omitted most of Abstemius’s fables. Compare the fable of the sheep asking why the pig squeals, #302.
