There is an excellent post over at THEROXOR showing 23 logos with hidden meanings. They are all cool but I was especially surprised to see the all familiar Amazon logo:
From the post: “This logo doesn’t seem to hide much at first sight, but it gives you a little insight in the philosophy behind the brand. First of all, the yellow swoosh looks like a smile: Amazon.com want to have the best customer satisfaction. The swoosh also connects the letters a and z, meaning that this store has everything from a to z.”
Make sure you check out the other 22 logos as well.
