With our middle daughter we saved all the college mail in a box. I’m not sure she read any of it, but it made an impressive pile. Once she had made her college decision we made a funny video of her college decision using all those brochures. It ended with a post-credit scene of her dumping all of the brochures into the recycling bin.
We sorted all those mailers by color, prestige, geography, headlines, claims, artistic qualities, thickness, etc. One favorite was the batch of free applications from different colleges that all arrived within a couple of days, with nearly identical fonts, text, and envelopes. Clearly they all use the same mailing/marketing service.
