Love this puzzle, artofhiddenmessages! However, when you say "look closely," does that mean I need a magnifying glass, or was that just a broad statement?
Meg, to get started, no you dont need a magnifying glass. Look at the various aspects of the painting, look for anything that may look out of place or patternistic. Once I got out of the weeds of the details, something jumped out to me that I was able to interpret. I now have confidence that this is indeed solveable!
