They are a "Novelty" but they are still collected as you show here.
If you were into "John Deere", you may find hundreds of them in different styles. You could also collect all of the USA Presidents if you like.
Peltier made the “Picture Marbles” a thing and they are still very collectable today—just a tad, tad, tad more vintage than what you are showing here.
“Collect what you like” is my motto.
Pink Floyd sold an album that actually had marbles in a pouch included with some other mayhem as well.
Research these Floyds "just in case". I am sure that there are copies out there. (These are still quite valuable)
Marble--On!!
