I wonder if the cafe that has the first art has karaoke ? I wonder if what's inside the glass has to do with spirits.... as in alcoholic drinks? That was the best I could do.....
My husband had an artist friend many years back. He would sometimes give us a print of some of his work. I remember there was a big one where it was a man's head (somewhat) with many colored wires hooked into his face. I remember my husband asked him what his thoughts were behind it, what he was trying to convey and the artist said there was no meaning. LOL !!! So does every piece have one? Maybe not or maybe they don't always share where they were coming from.
I wondered if the PFT had something somewhat related to an NFT, only on a wall. I made that up, but....
I love seeing street art.
Your ideas make a lot of sense, I will have to swing by there againa nd check if they do karaoke there
a good point maybe every piece does not have a meaning the artist is just going with the flow
