There is a table dedicated to various items requiring cast autographs. Whenever a cast member enters or exits the set, they come by the table to sign the items.
This is one of my favorite photos of the entire set. Gene Stupnitsky, Justin Spitzer, and Lee Eisenberg. Da boys backstage.
Oh and if you happened to read the final question submitted for Lee and Gene’s Q&A for ‘Dinner Party,’ it was signed by someone named “thespitz.” Justin denies it was him, but does confirm that it was written by someone on The Office staff. Those pranksters …
When I saw Rainn for the first time that day backstage, he said “Congratulations on the acquisition!” To which Kate replied, “That was a prank, dummy.”
