You made very good points. It’s true the pen picture is from May 10, but have you found a corresponding released EO with those letters?
Read Q #1381 “Follow the pen. Already written? Letters left visible to match.” This could mean that the White EO is already written, dated AFTER May 15. When and if the corresponding WH EO is released, if the letters match, it would show that Q had very accurate inside information. Time will tell.
I don't know about the date correspondence. The photo was posted May 10 (you say, I believe it, didn't check for myself), and if the photo is some kind of presidential order (not necessarily titled "Executive Order") then it existed on 5/10. Are you saying it was post-dated when the photo was taken? Or the photo is of a draft, for show? Or the photo is an undated order, date to be added later?
My simple point was that if one has two papers with different engraved letterhead, one knows they are not the same letter without seeing more. The anons got focused on the body/text and overlooked the engraved letterhead.
And a Wednesday 5/16 Q drop suggests the declassification order couldn't be promulgated until after declassification was demanded by others. Not said in the Q-drop, just my remark, the order of events is for optics, not required as a matter of law. If the photo on 5/10 is some sort of "precursor memo," we just take Q's word for its contents. In other words, the 5/10 photo doesn't prove Q authenticity, it is just a prop to gin up discussion about getting declassification on the material Nunes is seeking.
