If it uses a postage stamp and is cancelled, it has to be "officially authorized" doesn't it?
Not necessarily.
USPS rules allow you to affix almost any other stamps (official or cinderella) as long as they are far enough away from the actual stamps used to pay for postage so that there is no confusion as to which stamps are being used to pay for postage and which stamps are for "decoration". Otherwise, you would not be able to use Christmas seals... on your mailings. I've never known any postal clerk to actually enforce this rule (i.e., reject a mailing because a cinderella/label was too close to the actual postage stamps.
A few dealers will occasionally decorate their mailings with some cheap mint foreign stamps. You may also apply whatever cancel you would like on the extraneous stamps.
That being said, I don't know if those cancels at the upper right in your pics are actual USPS commemorative cancels or a private cancel. Somebody who collects commemorative cancels might be able to tell you. The cancels over the local post stamps are clearly privately made/applied.
