You'd think this would be easy to find, but alas, I cannot find the logo for Comet!
Anyone have leads?
That logo was just uploaded today to this site so whenever they get around to making it available you will be able to find it here.
Incidentally, the Comet logo was found by doing a Google search for the annual report for Prestige Brands, the company that owns Comet. So if you do a google search like this:
"Prestige Brands annual report filetype:pdf"
You'll get a series of PDF documents that include vector copies of the logos owned by this company.
