A lot of collectors of Vintage Photos like to specialize in themes or categories. This Funny Photo of a man wearing a floppy hat is a good example of an photograph that will fit in several groups. Obviously, this will fall into the Portrait Photos category. It also fit into the Funny Photos category due to the fact that this man appears to be acting silly for the camera.
Whatever category you put it in you have to agree that this is a Unique Photograph and I think, for my collection, it will be placed in my Funny Photos box.
