Good find.
Logo designers do not come up with such similar things unless they share a considerable amount of parallel guidance from the buyers. They don’t just come up with these things on their own in a vacuum. I’m not a logo designer, but I know from acquaintances that a designer gathers an enormous amount of info as to what it is the logo should evoke in the viewer. This isn’t a goofy blooper or creative happenstance.
I’ve taught logo design at university level. You are spot on in your comments.
I’ve read that a few times today, thanks for the post here
