First editions, 1936 (1 & 2), 1937 (3), 124pp each volume, plates, card covers, dustwrappers. In generally very good condition with a little foxing to the contents & page edges of Third Series, the dustwrappers a touch grubby and worn. The illustrations on the dustwrappers (which are repeated on the Contents pages) are woodcuts by Eric Ravilious - the one for the Second Series is of Hull's Mill, Castle Hedingham. Uncommon booklets, a complete set of first editions is uncommon.
