Oh, yes, at least the ones I have seen have them. They come with the passkey to withdraw funds and instructions on how to do it.

@williambanks posted a great site to make them:

I would imagine if you had simply hand written some, which I'm sure can be done, they may not be taken for anything truly valuable. However, I believe someone familiar with bitcoin and altcoin wallets would likely recognize a wallet address and a passkey.
