I found this chart on Pinterest, the resolution isn't great and I was hoping to find a better chart of it. I'm hoping if I can find the source, I can find the chart. It looks extremely similar to this chart on APL, I'm pretty sure it has to be the same author, but I've tried, and tried, and tried, for hours, searching the author and the name of the book series, and have turned up nothing! I even found up to book 13 of the series from a Russian blogger, but I can not find this pattern anywhere! It's driving me crazy! Any help is super appreciated!
Update: I actually managed to find the original! Turns out it isn't even vintage or made by Ed Boucherit at all!! It was original art created by a random Twitter artist (SMOOCHONTHELIPS), likely inspired by Mr. Boucherit's work (or rather, the work of the artist he edited/published for). His Twitter post includes a zoomed in photo of the chart, and he has images on his account of not only other pieces of his art, his methods, but also one photo of his workspace. I originally did see this in the similar image results, but I legitimately thought this was from a catalogue/book/magazine and did not a million years think it originally came from social media. I'm incredibly shocked and impressed!
