Forgotten Era Advertising

I've dug through several garbage piles left behind from the forgotten era, and have come to realize that they printed a lot of things that are now completely useless, or make no sense. Mainly thanks to the advertised products being no longer in circulation. I'll add to these as I find them.

Some common examples

• Data Cores Limited bill boards: Also called DCL, they advertise my Bio-Processor Pad N15 DCL-1800, normally in strange ways. Examples being a strange image of the pad growing from the bud of a flower with the words "Express that which is inside!" in bold red lettering.
• Unmarked black booklet: Inside the text had rotted away except a coated page with a picture of a purple cylinder that simply says "Experience. True.=" the page is ripped at that point.
• Unknown soda adverts: "Everyone is drinking it, buy yours today!" The name of the soda is unintelligible, the image depicting a can pouring a brown liquid into a ice filled cup.
• Unrelated Poster: A poster behind a clear plastic panel. A picture of a drawn, exaggerated awoken that seems closely related to a Cag on it. The proportions of said character are completely wrong, with them running from an explosion in the background. The text on it reads "One boy's dog saves the world..." Below it in red and yellow font "Fido!" further below that "Coming this fall, 3422"
• Mints ad: A half rotted poster with a picture of an open tin box "F-f-f-fresh as ever" is printed on the top. The bottom is torn away.

Purpose

Obviously it was to sell some sort of product. At least most of them seem to be. Others seem to be trying to advertising a show or service.
