The image is of the style of the Tobin cards mentioned.

But that looks new to me, I don't think it's very old at all. Have you illuminated both sides with a black light? Please do that, and let us know what happens.

To me, from the image you posted, I think it's very new, its worth would be as a book mark or an object lesson. I'll back off from that after I hear about it not fluorescing. If it was scanned while in a holder, scan both sides again without the holder.
