These pictures are actually 5 different books that we have made into photo albums. They each contain photo sleeves for either 4x6 or 5x7 inch photos. Some of these photo albums are bound with leather on the outside, others are bound with metal rings, still others have posts and hinges for their openings and finally we have some that are bound with hemp to a tree branch. All of our albums have wooden covers. Some of the albums are set up to be able to add additional sleeves while others are meant for a trip, a moment, a specific time in life, or event. While the photo sleeves are secure, the pictures can easily be changed out with the time.
