At the beginning of the computer era, not everyone knew how to use a floppy disk (maybe now not many people still knows how to use them!).
In 1980, the software company Beagle Bros started to produce software for computers (mainly the Apple II) and used very funny documentation and graphics. Many of them can still be found in the Apple Archives Repository. On the back of their floppy disks they’ve included this brilliant graphic with 9 signs of what you shouldn’t do with a floppy disk.
I didn’t expect this was going to be the second sign with an alligator tag!
If you read Spanish, the info was found in this article.
