From the context of this signature you might assume that "Val Ay" is a little-known Shuttle astronaut. In reality, according to the item title and description at least, this is actually supposed to be the autograph of famous non-shuttle-astronaut Neil Armstrong!

At least the 'winner' of this auction gets a nice magazine to read. With any luck maybe there's an article inside about how to spot Armstrong forgeries...

E for effort (wrong cover shot)
