This is a picture of a little person, Edward Garrett, who played a baby in the farce "The Little Stranger" on Broadway. So, the picture is not as weird as it looks. It is a picture of a man, not a child.
We lived behind a church where my little brother was called over to sing in front of the entire congregation. Gary loved singing just like this little boy in the picture Out of the mouth of babes there is perfected praise."Sing Unto The Lord" !
