Several months ago I bought this, got it home, hit the front with a black light, noted no glowing, and tossed it in the closet. While searching the internet a few days ago, I came across the Legendary auction in which a 1/1 of this had been sold. I had been thinking this was nothing but a less than hundred dollar...thing. I e-mailed R. Lifson (very generous with his time even during the then current auction), and he said he wasn't sure but was concerned about the authenticity. When I couldn't find a photo of the back under a black light, realizing I didn't do that, I got the thing out and did that...
1. If the card is too dark under the black light, there may be a problem (I had to over-expose because in the normal way I do it, the thing was not even visible)
2. Check every bit of the card, not just the card as a whole
3. Always use it on the back too.
Had I known how important the real version of this "card" was when I bought this, I would have been very skeptical like with regular cards.
Note the circle where the thing should be hung from a wall and the edges in the front photo with the black light.

And here it is...I've been had!
