US Special Delivery E1 - How Many Things Are Wrong?

I got this very cheaply, so bring it on. How many things can you see wrong with this (supposed) MNH sample? Note that the fault in the upper left almost looks like they used a corner protector to hold it in place.

The added corner, regummed over a sealed tear and probably a filled thin; there are at least 4 added perfs at top (possibly 5), and it probably has a cleaned cancel. Aside from that it's gorgeous!

I often see Special Delivery stamps in discount postage lots. Note that these are not valid as postage under DMM 604.1.3(a)

1.3 Postage Stamps Invalid for Use

The following are not valid to pay postage for U.S. domestic or U.S.-originated international mail:

a. Postage due, special delivery, special handling, and Certified Mail stamps.

b. Stamps of other countries.

c. United Nations stamps, unless on mail deposited at the United Nations, NY.

d. U.S. stamps that are mutilated or defaced; cut from stamped envelopes, aerogrammes, or stamped cards; covered or coated in such a manner that canceling or defacing marks cannot be printed onto the stamps; or overprinted with an unauthorized design, message, or other marking.

e. Nonpostage stamps, such as migratory-bird hunting and conservation stamps, U.S. saving and thrift stamps.

I'll keep that in mind before I post a letter using 5 E1's.

Well, for a buck, I'm still happy. (Quite the opposite of Mrs. Lincoln, I am sure.)

(Come on ... it's stamp collecting. Our humor, as well as most of my stamps, get pretty warped at times.)
