You can see these actual menus on display in House on the Rock's "Heritage of the Sea" room (the only with the massive octopus/whale). They're posted on the walls around the perimeter of the room along with lots of other boat paraphernalia.
In some of these situations the intention was for the child's face to be centered in a locket or in an otherwise masked/matted frame. The child's holder's hood and clothing become the background of the photo. I don't believe we were ever intended to see the photos as whole compositions.
The very fact that this date is "the most boring day of the 20th Century" makes it an interesting day. Since it is so interesting, it can't possibly be boring.
