I haven't seen a 7.5" diskette.
Assuming that the picture is not to scale,...
The floppy doesn't have an index hole.
The notches on the leading edge are consistent (albeit not accurately
placed) with the write-protect notch of an 8" disk.
Further trivia:
On "The Computer Bowl" a few years ago, Bill Gates' entire team could not
state where the write-protect notch was on an 8" diskette!
For our Computer Faire booth, we used to have a 5' inflatable toy
Tyrannosaurus (wearing a valid admission badge as VP of Marketing) holding
an 8" diskette with a bite out of it. One time, a little kid walked up
and said, "that's not real." My assistant said, "that's right,
it's just
a plastic inflatable." The kid responded, "not that, you dork, that disk
is fake." Bob said, "No, that's a real diskette; they used to make them
like that." The kid rolled his eyes and said, "yeah. right." and walked
away.

On the original floppy's being in cardboard...
I have a very ancient Dicom 7 1/2 inch dual floppy disk system, and some
media for those
bizzare Memorex drives. Indeed, they are made from cardboard. Its been
impregnated and
pressed into a composite material, but it clearly is cardboard.
Does anyone on the list know anything about these ancient 7 1/2 inch
Memorex floppy drives?
