Cassell & Co., 1950, Fourth edition. Includes signature of author. Hardback bound in red cloth with titles in black on spine; 8vo., 704 pp; illustrated D/J. Book condition: Good, corners and ends of spine bumped, slight foxing to edges of text block but otherwise clean, bright and tightly bound. D/J condition: Good, nicked and worn at edges, 5 cm tear on upper front (see image) not price clipped. An omnibus of 5 volumes: The Innocence -, The Wisdom -, The Incredulity -, The Secret - and The Scandal of Father Brown, containing 48 of the immortal stories. What makes this volume collectible is the presence on the ffep of a possible signature of G K Chesterton (see images). It is written on a rectangle of pasteboard, which appears to have been clipped from the lower right corner of an invitation card, and pasted onto the ffep. While we are unable to guarantee its authenticity, it bears strong resemblences to online images of his later signature.
