I do.
As a kid, I'd go through those send-me-more info postcards in some magazines ("Computers & Electronics" was probably one) and circle the identifying number of every ad that I was interested. Which resulted in shelves and shelves of catalogs and brochures that I read through. Lots of neat new stuff that I wanted to know about.
(This eventually morphed into getting some wholesaler/distributor accounts, and their catalogs, for some of my childhood businesses.)
When I look at old magazine ads today, lots of neat old stuff that's interesting for different reasons than at that time.
For example, "They were already doing that back then?", "How much did that cost?", "How'd they do that that with tech of the day?", "I remember drooling over that prohibitively expensive, now-obsolete, thing, and I'm strangely still drawn to it.", "Now that I understand grownup things, so that's how these different brands were positioning".
Once Web ads started, in the mid-'90s, I was developed a Web-scraping application, and I went to a lot of trouble to preserve and present ads that came from where I scraped the info. Then ads secretly spying on people started becoming a thing, and it's hard to convey how offensive this was (surveillance of ordinary people was something done by evil geopolitical adversaries, of current and past history). So I started working on Internet privacy, and me -- the kid who loved ads -- ended up writing thousands of ad-blocking rules. https://www.neilvandyke.org/junkbuster/
As for appeal of ads today, I don't have a good intuition, because I know it's not just a display ad, I understand some of the business around it, I know that the Web site is selling out the privacy of its visitors and how that's abused, etc.
