These 2 soft cover books/booklets are very old, but also very useful.  Each is packed with hints, tips and advice for canning and storage, as well as many tried and true recipes.  The Kerr Home Canning Book has a copyright date of 1946, and The Ball Blue Book is also dated 1946.  Each has had it's stapled edge reinforced with tape, but both are still in very usable condition .  These vintage gems will ship for free within the domestic United States.
