It should be noted that the USPS, UPS and Fedex, are starting to use electron beam bombardment to knock-out any possible anthrax spores, in letters and small packages. It is often ignored how such can cause images to form through some items, not just film, but some paper, and potentialy playing cards as well.
I have notices new boxes of cards are showing up with the card decks stacked flat inside the bigger box lately. And I had some experience back in the 1970s knowing one of the designers of a very cheap industrial x-ray system, with several patents to his credit. He used to play around with this and some common techniques for slightly increasing one's visual color range. Wouldn't play poker with him, nope, not me! This is possible with several of the exercises that new agers mention using to see "auras." You sometimes also see meats, at high end grocers, like Safeway, where irradiation will cause a shadow of the UPC label on the marbled sections of a steak, for example.
Back then it was a prank for him, but now that things are getted bombarded to save us from, well gee we forget that the total exposure was 20 people and only 5 died, I think we should examine the possbilities.
The shadowing would mostly be in the violet to lower ub ranges and be mostly from bombardment changing the polarity index of the plastic coating of the cards in proportion to the shadowing created by the design of the face side of the cards.
Until recently this post would have only brought ridicule and scorn, but even with the increase in noise I hope this post can be an example of also being more free to discuss more edge topics, but I for one am very willing to try to seperate the data from the bs, even about topics like auras etc., to see if maybe slightly extending one visual spectrum a bit toward the uv range might be enough to read "through" the cards.
I don't have the upper violet accuity this would take.
And yes if it were possible for me to join I would have held this back for black or green chip, or the workshop.
