This one might be a bit hard to read:
It says:
Dan, I’m not supposed to tell you this, but this guy is the one behind everything! – Michael Giacchino. (He made the “O” in the title into a man with his mouth open.)
Then, conductor/orchestrator Tim Simonec made the “L” into a baton, and wrote “My baton, Tim Simonec”
And finally, show creator J.J. Abrams signed his name – but only after writing what he thought of Michael. 🙂 Hehe
