My wife and I looked through all 44 of the images provided at the link, studied them closely, and tried to determine which ones had been posed and which ones were snapshots of a real activity. It helps to bring out some of the details in the photo, at least to us.
I also used to enjoy the “write a caption” contests that were in the newspapers years ago, so we had a silly time of making up dialog that probably was not what they were saying (or thinking) when the photo was taken. We had fun with it. Thanks for posting.
