This is something I found in Stockport's fantastic monthly Vintage Village fair. It was from Agnes Darling's stall, and she deserves a mention, as I seem to find something great there every month.
The Kingdom Under The Sea is a 100 page children's book first published by Jonathan Cape in 1971. It is Joan Aiken's retelling of 11 traditional Eastern European folk tales (some of which are based on Ivana Berlic-Mazuranic's 'Croatian Tales of Long Ago', a book I know nothing about, but I imagine should be worth tracking down too).
