I keep finding them around the Wasteland, but have yet to find a purpose for them. Are they a red herring item, or do they have some use?
They have no known use. They can't even be scrapped for materials.
Arguably they could be used for "decorating," or collected to see how many you find (and so on), but serve no in-game function - the same as burnt magazines, burnt books and some other miscellaneous items I can't think of off the top of my head.
