I think in order to meet this criteria, the printing gaffe would have to be pretty severe indeed...either that or the card met with some serious trauma during it's lifetime (ie...a bad soaking). But either way, I'm eager to see what might be out there that falls into this category.
I'll get us started....here's a Home Run Kisses Proof. HRK's are typically two-color sepia and brown colored on a light cream card stock. This card, somehow was printed in black on a thin white paper.
