I suspect the signature is printed.
#1 and #2 here are identical (I imagine that's a different view of the same piece?).
However either #1 or #2 (might be the same piece) are not identical to #3. Far from it.
Two different autopens? Is one an autopen and one authentic? 1 and 2 are not the same as #3.
Probably AP. It's almost impossible to get a sitting President's autograph.
