The cover is almost exactly the same as the regular edition except it says “Limited Foil Edition” where the regular edition has the $2.50 price. The title is also a different color, darker, but I’m color-blind and can’t tell exactly what color it is (Edit: My man Knight let me know it’s green. Somehow he was not laughing at me when he told me this). There is definitely no foil, I checked. Not sure what the story is there.
Both are pretty cheap but it’s harder to find the foil version unless it’s an eBay auction that has a decent picture of the book. I got mine by accident in a larger lot of books.
