In the 6th edition Starter Set, the guided game comes with two color-coded playmats. You can also find (very blurry) screencaps below, and in this instructional video. (I've linked it to the appropriate time, so you should see both playmats within 5 seconds.
I'm trying to find art, source files, or high resolution images of these playmats, so...
What is the name of the art (or card) wherein the gold wizard is depicted on each of these two playmats? If that's unavailable, is it possible to identify the artist?
