Here are some examples from a 2010 model railroader. https://photos.app.goo.gl/RvRzECgs7MaTo7tP8
Some, especially the Kato model Amtrak one, have some aspects of an aspirational ad, but I don't know if I'd condem them as such. They usually, as the Kato one has, information about the specific items that are now available and often some "ambiance" information that many hobbiests, especially people new to the hobby like to look at.
I don't mind ads like these as they're not designed to make you feel as though you need to purchase something to be better and they're not in a public space. They're they're to matter-of-factly says a service or product is available.
I could also show you the local pennysaver or Craigslist. All of those are also add, but they're not the "aspirational" kind. They're more matter-of-factly that someone is selling so (used) item, or provides some kind of service, or that there is a garage or estate sale at such-and-such address. How else would this information be made readily and easily available?
(To the extent that bad products get more enthusiastic advertising, in a perverse sense viewing ads might actually make you a more informed consumer if you deliberately avoid any product with slick marketing. However I cannot advocate for such an approach because I think the theoretical advantage here is washed out by the practical reality that advertising will effect you in ways contrary to your own interest, but in line with corporate interests.)
