DC/NATIONAL COMICS SUPERMAN item (Parma)

DC/NATIONAL COMICS.
.
.
SUPERMAN 1 of a kind or very few survived, according to the comic collectors I contacted & asked.
NOBODY that I have contacted over the last few years has ever seen one of these.
The Superman website https://www.

php knows nothing of this item.
I'm pretty sure it's a clip from a DC Comic's magazine rack specific to Superman comic books.
I had this since I was a kid in the early 60's & I had this on my banana bike spokes for a short time in the early 70's.
I'm glad I took it off.
I didn't want to lose it.
It's in excellent condition.
