The part about the Ice Cream parlor:

Green's Dark Chocolate: So Good

(the blue boxes and the red boxes on the side are Green's Chocolate, but I don't know what those other red boxes in the middle are)

Superior Quality Kiddy Cone: 1 cent

Dimwit's Single Scoop of Lazy Lemon: 3 cents

Duke's 3 Scoops of Patriotic Duty: 5 cents

Earnest Eagle's Li'l Solder Sundae: 3 cents

All that time looking closely at those made me hungry for ice cream. Also, Dimwit and Duke seem like Columbia's propaganda tool for kids to aspire for patriotism ( Dimwit being a unskilled patriot, Duke being a skilled patriot). They not only appear here, but also in a red advertisement outside of the beach; its red, and their stances in yellowish white make them stand out, with a barely visible title that is "Dimwit & Duke". Of course, those figurines are similar to those from the Gatherer's Garden.

The room with those people in white could be a chapel for worship, either for the Siren to resurrect their dead, or to listen to Comstock, since a poster refers to him as a prophet, which makes sense with all the Tears.

Elizabeth's outfit could be what she was wearing when Booker first finds her, since it seems like its only once she wore this, and she did wore something similar in those photos. I can't be certain, but if you look closely, there's something long behind her neck, possibly her hair tied from behind her neck, which she did have long hair in the photo. Its possible to speculate, but I think due to how important she is in Columbia, she had to be in disguise by cutting her hair, and wearing that blue outfit.
