Trusting someone else to print you out wallet private keys is just insane - even if the OP of this thread is trustworthy, it sets a dangerous precedent allowing any asshole scammer to come along and repeat the trick.
I have added a means to verify that my sheets are genuine, I'm stamping them with my own fingerprint. See
http://casascius.com for a reference fingerprint.
By doing so, at least I have raised the bar upon any asshole scammer. I at least have a real life identity to put on the line!... something scammers are rarely willing to offer.
