Chuck RossElliot, thanks for the very concise summary. On all the cards I have with this effect, the two sides are a perfect match (as if it was some sort of bleed-through, though that does seem unlikely). If this did come from stacking sheets (which seems more likely), it sure seems that someone in quality control would have altered whichever step of the operation was causing this. Or maybe since it was only 1 cent cards for kids they didn't really care.
