However, the art was actually printed reversed left-to-right. In the Sixth Edition version, the reversal was corrected.
How can you tell that the art was backwards? As you can see in the high-resolution art, the artist, Carol Heyer, inscribed her last name on the binder of the book that the Sage is reading. In the Alliances version, her name was backwards!
