Well, based on your autograph and the preprint on the poster, i'd say it was a secretarial. There are many differences in the two.
First, the A's are completely different. Ashley's A is more loopy when she does it, not straight on the edges like in yours.
The Y also looks very different. The Y on the poster is very narrow and a close loop, while yours is very open and wide.
And im pretty sure when she signs, she always includes a T to signify her last name. I met her twice and got 4 autographs. all have a T in them, even if they dont look like a T haha.
