So many of the pictures are not annotated and there are very few clues about who, where, when they were taken. That's the case in this instance. The pictures were together which may or may not mean anything but it's all I have. Both pictures look like they date from the 1920's or 30's.
The first picture is of three unknown men and if you look closely there is someone sitting inside. The boat is named "IOLA" and registered in New Orleans.
The next picture is stamped on the back "Made by Purple Pigeon Studio P.O. Box 2 Gulfport, Miss." The baby is wearing a long dress with a long coat. The appears to be covered with lace and had rosettes on each side of the face. The hands appear to be covered but in what I can't tell! Doesn't look like gloves or mittens.
