I decided to do a test. My wife (who for some reason isn't interested in most of my older computers??? :-) hasn't used an Amiga or seen it boot from floppy.
I showed her the pic and asked her, "If you saw this on a computer screen, what would you think?"
She said that she'd look for a disk called Workbench to insert into the computer.
Sounds like it accomplished it's task.
(Note: She is very computer literate, just not retro-literate.)
