That does not sound like something to deliberately leave untouched for 14 years either.  What kind of wallet software was reputable back in 2011?  Anything would be vastly inferior than the ones that were developed later on, in terms of security.  Imagine watching your net worth go from $30k to $300m and keeping them in a paper wallet.  Lol!  If I was him, I would have moved them into a BIP39 seed phrase at least, if not multi-sig / BIP39 with passphrase.
