Both pictures September 18, 1921. No other caption. Margaret is on the left in the picture on the right. The other two are New Haven cousins. Read on...
All four of these pictures are Sept 18, 1921, New Haven Conn. So these are cousins, Albertine's sister Lottie's kids. The captions are not much help. Upper left: "Speeding". Upper right: "Don't we look nice". Lower left: "Walter" (another cousin I suppose). Lower right: "Milk Maids".
September 25, 1921. The captions are very faded. I think the left is "Leg show" and the right is "Feel good". I think Margaret is on the right in the first picture, and Marie is on the right in the second one.
This is the end of the first photo album.
