Signs and Symbols are EVERYWHERE
Here's an easy one to start with, though I did not see the arrow between the "E" and the "X" until someone pointed it out to me.
There's a lot to unpack as far as the levels and layers of meaning. Some of the hidden meanings we may never know.
This investigative experience can be lots of fun because the best part is that you start to pay attention to the subtle language being expressed and it no longer has a hold of your subconscious.
Good luck!
