I don't think its a gap.

Exactly. And I'm pretty sure as a kid I just imagined that's what a loom was.

Wait your telling me it didn't have the basket like thing? Could it be more likely they changed the logo?

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.

But who drew the cornucopia???

I can't believe someone sketched that in to explain a Mandela event

that, plus it just looks better with a cornucopia. Like if apple never had the bite on the apple and someone started a rumor that it actually did, that would be easy to believe because the bite just obviously looks more like a logo.

Just having a bunch of fruit doesn't give any connotations to textile, but the cornucopia adds something that bridges the gap so the logo isn't so out of place.
