I believe this is secretarial as well. Its a different secretarial person than the one we normally see. On this style you will see capitol E's a lot in the "dedication" area. MJ rarely ever wrote a Cap E, unless it was at the beginning of someones name.
Someone showed me this one the other day. I am not sure who wrote the inscription but its not in his handwriting, every letter is in caps, and thats not his style at all.
Here's a note below that shows what I've normally found if he uses a cap E (they look like backward 3's). And are usually always at the beginning of a word. See if I can find a few more.
This one below was part of the wrongful death lawsuit against AEG, notes in his house preparing for comeback. Note backward 3's twice for an E
Here's one that just shows what his normal inscriptions looked like.
Another below, one to Karen Faye his make-up/hair artist, where you can see the writing looks nothing like the ones that have the cap E's.
Just some writing styles of his, he had a quirky style, mixing the upper/lower case.
