We use the 4x6 photo holders.. The plastic ones you can find for a $1 or so. I cut 4x6 white card stock, after each autograph was signed we put it in the holder. When we got home I printed the photos and slipped them in. Just remember to take your photos horizontally. Later I will probably move the autographs to a scrapbook, but for now, they are in an easy to carry, kid friendly book
