Do you have a certificate that proves the authenticity of the signatures? Not trying to say you would fake it but I know it happens.
Well, I can prove that I definitely own the first Signed Monarch deck distributed by Theory 11 because I won it in a Saturday Night Contest. Here's the link to the original page,

The rest of the signed decks went up around a month and a half after the contest. That's about as much proof as I've got, aside from the video that I used to win the contest.
As for your question Don, there are five signatures. The names that I can read are Morgan Freeman, Isla Fisher, Dave Franco, Mark Ruffalo and Jesse Eisenberg. The deck box is signed on both the front and back, and on both sides.
I hope that answered your questions!
