'Authorized Signature' in fine, micro print to give the appearance of a solid line. To the common check writer it is just a line upon which to sign his/her name. To the banking industry, it is the authorization, given by the natural person/owner, to allow his/her transmitting utility(corporation) to fulfill a contract. For you see, only a corporation may contract with another corporation. Look it up.

This is why the LAW cannot be justified or proven, by any whom are questioned to produce it. It's far easier to say, "Because it's the law," than it is to tell the truth, which is "Actually, we can not tax, for example, Alexander William Rose-the natural, sovereign person. We can only tax ALEXANDER WILLIAM ROSE, his authorized, by SSN, transmitting utility.

In most, if not all, cases you will find the bank's stamp on the back.
It should say, in varying terms the following:
"FOR COMMERCIAL USE ONLY." This means commerce. This means corporation to corporation operations. This means you. You will notice that your name is also printed on the back, to accompany that stamp. It IS stamped in ALL CAPS.
