wow, didn’t know that- thanks for sharing that- will definitely have to look further into the secrets - Even Van Gogh had hidden things in his- one of his Paris outdoor cafe scenes with electric yellow lights, is said to be actually symbolic of Christ’s last supper (Gogh was a preacher at one time in a coal mining town- lived in sheer poverty, and darn near died serving the miners0- I had a huge book on him when i was a child- read every page, which included all his notes to people, mostly his brother- fascinating read really)
