Physical AM stock Certificates

I thought this would be kind of a cool idea. Since a share of AM stock can be tied to a Btc address, you could print certificates (in the same way you would print paper wallets).

I will have to admit that I know nothing about printing certificates like these, (would probably need a scratch area where the private address goes) and I lack the expertise to design a cool certificate that would be used.

I understand that dividends could not be realized unless you scratched it, and that selling it would transfer dividends as well, but it may be fun to be used as a gift or the amount of dividends could be included in the sale price when sold to another person.

I thought this would be a cool idea. If anyone is interested on working on something like this please let me know and I can help how I can. Also let me know if this is something that couldn't work, as I may be overlooking something very important.
