You can buy pre-printed timeline pics, but you don't have to. We didn't.
When we first did MoH years ago, we used the little timeline figure template she had in the book. My girls made each figure themselves and we glued them into a timeline book we made ourselves with a binder and card stock.
I love going back and looking at that timeline binder (we still add to it) and I love seeing all the people they made. It beats pre-printed ones any day. Their handmade figures are SO cute and the book is very personalized. I love seeing their drawings from when they were younger... some are very funny!
If your student likes art, let him go ahead and make his own figures. You won't regret it. It doesn't take much time at all using the little template dude she includes in the book, and you'll have a wonderful keepsake you can continue to use even as he gets older. When we add to the timeline notebook now (with my ds), it's clip art or pics from on-line, because drawing/art is very hard for him. No nostalgia, or personal touches, so I'm glad I did that with the girls when they were younger.
