I just checked some old clothes I've got from the 90s. No cornucopia. Wonder if it was on the packaging or ads or something

You probably learned cornucopia from thanksgiving, that's how I learned it. Also, google cornucopia and basically every image looks like the fruit of the loom logo but with the horn behind it. It's pretty obvious that people are so used to seeing the cornucopia imagery that when it's combined with the fruit of the loom logo their brains go "yeah that looks right" and just assume that it must've been that at some point.

Mandela effects are fun and I understand the appeal but anyone who takes them seriously is straight up just not using their critical thinking skills.

Mandela effect stuff used to be just weird and silly, but in the last 5 years or so the internet has become centralized enough that it is actually possible to scrub all records of something from history, especially if it's something innocuous. That makes it very difficult to trust the corporations when they say "no, our logo never looked like x" when they might be actively lying about it.

Maybe their machine learning determined that in 3-5 years cornucopias would be deemed a symbol of oppression so they removed it to get out ahead. Or maybe some rich assholes son who was gifted a job as head of marketing just inexplicably hates cornucopias and wanted to scour them from the company. Or maybe through sheer incompetence, no one properly documented the logo change and everyone who was in the company has since moved on, so now everyone is like "hey according to our official records it was never like that" and they stick to that out of sheer corporate stubbornness.

Point is, for whatever reason, companies now have the capability of gaslighting people about this. You can still look up their old patent history, but that's about it unless you randomly find old pictures that happen to contain it.

I still think most of the time it's just common misremembered things from childhood.

Just so you know, that brown thing is called a cornucopia! Literally "horn of abundance" in Latin.

Or it wasn't and you're just mistaken. You can find vintage underwear and t shirts on ebay from fotl back in the 70's and 80's right now. It isn't there. Also, snopes.com deemed it false.

it never has been

I don't think its a gap.

That's the weird thing.

In my country cornucopias have no cultural significance or association with piles of produce. Still, every time I have talked Mandela effects with friends and acquaintances and asked them to describe the logo for me (stores in my country would sometimes have imported t-shirts from Fruit of the Loom) they describe it as "a big pile of different fruit with that basket-thing behind", not even knowing a word for the object. When I tell them there is nothing behind the fruit pile, they are in total disbelief. Like many other commenters in this post, I remember asking my dad, after buying a pack of t-shirts, what that thing behind the fruit was, as I had never seen anything like that before in my life. I must check up with him someday if he still has any surviving t-shirts left, though I doubt it, since they were cheaply made and broke often. It's also the weirdest feeling, that the logo with the cornucopia in this post is identical to my memory of the logo, down to the smallest detail, and is exactly how all I have talked to have remembered it as well.

It's the same thing about the Monopoly mascot and his monocle. People try to explain it by saying that people conflate it with some Peanuts brand mascot, but in my country we have never had that brand in our stores nor any other brands with a mascot like that. Still, I am not as astounded that people in my country and myself remember him with a monocle, as there have been plenty of characters in movies, series and cartoons, foreign as well as domestic, that, when sporting a tailcoat and tophat, would always wear a monocle to match. The whole set is so broadly associated with aristocratism, that you would fill in the gap, so to say. Nobody in my country would say the same for a pile of fruit, unless it was a bowl we were talking about.

Ditto, but I had a spooky event preceding that. A black robed guy wearing a wide brimmed hat (think Vatican Elite or something) walked into my uncle's bedroom when I was a kid and held up two white T-shirts from Fruit of the Loom on brightly colored plastic clothes hangers, and said:

"We're thinking about changing the logo, do you prefer this traditional one, or this modern one?"

And, me, being small child babu and scared out of my mind by having a tall, pale, black garment dressed figure in the room with round sunglasses went:

"Modern. It's the Year 2000 coming up, the new millennium. Everything has to change."

He laughed and thanked me for my time and then walked THROUGH THE WALL to leave, not through a door.

The next year, 9/11 happened, and everything changed. Still boils my brains.

I like this idea but it’s hard to believe that nobody can produce a pair of underwear or t-shirt from the 70s that they found in their basement/attic

its* color palette improves

Perhaps the more reasonable explanation is that you're misremembering.

More likely that your brain is just remember seeing cornucopias.
