I got an email today with realized prices from the recent Nate Sanders auction and an Iron Man 3 premiere poster caught my eye:

It has a gorgeous COA with a pretty hologram. The only problem is every autograph looks like a blatant forgery. The only one that comes close is the Stan Lee autograph. 

Now, I've seen these kinds of things on ebay, but never on an auction site as reputable as Nate Sanders. What could be going on? Oftentimes when these are on ebay it's usually the same deal: big summer movies or box office smashes, pretty COAs, tales of premieres, holograms, limited editions. They put a lot of effort into making these seem legit, and I guess it causes people to overlook the signatures themselves.

So where do these come from, and why are they now being recognized by established, reputable dealers? There's nothing I'm missing here... those are fake signatures, right? Are the letters/homogralms/etc. fake too, or are studios producing these as freebies and then throwing "secereterial signatures" on them?
