The price you quoted is for an oversized autographed poster.
What's wrong with this?
First, you neglected to say it's a poster, so that adds to the cost.
Secondly, there are other photographs included on that page, autographed, that are as low as $32, $45 and so on.
Yet you neglected to mention those, I guess the higher price is more outrageous to you so you want people to get worked up about it?
