Got to use the proper terminology, there's decals - which are transfers, and stickers - which are adhesive backed.
More reason to get the '59 authenticity manual kick started, CLC.
I was able to refer to the '57-58 manual for this.
If there's no sticker on the top there maybe a decal for the AC Delco filter element on the side. The '58 had one, and I got it from a decal guy, but can't seem to locate his info at the moment. Search online that's how I found it, if he's still in business. There are several vendors and the data is not always correct. They're selling them, not guaranteeing authenticity/correctness.
Some of the other brands had much more pronounced badging on the air cleaners. eg; I have a '50s Olds air cleaner for a stock 4 bbl and it has the rocket 88 logo on a foil sticker. I don't recall there being one for the stock 390 but my batting average has been declining with age.
