Was the paper wallet generated from a blockchain.info feature, or how did you generate it?

Just curious,
Thanks
Yes, I generated the 2 paper wallets as a backup wallet for the same wallet of My Wallet from www.blockchain.info

A paper wallet also stores public/private key pairs but they are printed on the paper.  Whats nice about paper wallets is that they do not exist on a computer anywhere.  So unless someone has physical access to the paper they cannot gain access to the BTC stored for that address.

Well, unless he stores a jpeg of them on his comp or the data is let in his printer memory or whatever  Cheesy.

I made a paper wallet backup for My Wallet in www.blockchain.info It has my www.blockchain.info user name, Mnemonic, Public key and Private key.
A few weeks later, I made another (second) paper wallet backup for the same My Wallet. I was surprised to see that the Mnemonic for the second backup was different. My questions are:
Why is the mnemonic different?
What is the Mnemonic used for?
Why do I need any other information other than my Public and Private Key?
Thanks for any answers.


Keep in mind that your online wallet stores public/private key pairs. 

A paper wallet also stores public/private key pairs but they are printed on the paper.  Whats nice about paper wallets is that they do not exist on a computer anywhere.  So unless someone has physical access to the paper they cannot gain access to the BTC stored for that address.

I gather from your comments you might have thought the paper wallet key pair was specifically for your online wallet.  They are totally different things and store different key pairs

A Mnemonic is just a way of remembering something. http://en.wikipedia.org/wiki/Mnemonic
