This is the 100th Anniversary Edition 1874-1974. Blue hardback cover. Book is in overall good condition given it's age,cover does show some marks but does not affect the book at all, may even wipe off but I have never tried. Pages are in excellent crisp condition. This would be a great piece for someone and loaded with poultry information. Book will ship USPS Priority. Please pm or email with any questions. Thank you for looking.
