It's not your fault / It's your fault.
Now for the first time you can decide whos fault it is... or send the card and let the recipient decide if it's their fault or not.
With an elaborate double score folding system the card can be left as is to read 'IT'S YOUR FAULT' or folded to reveal 'IT'S YOUR FAULT'.
Full instructions are on the rear of the card.
At last... the answer to who's fault it is!
