Tina Fey uses items from her real life to decorate parts of the “30 Rock” set. Fey, along with set decorator Jennifer Greenberg, took NBC’s “Open House NYC” on a tour at Silvercup Studios in Long Island City and revealed she hung pictures of herself from her Second City improv days in Liz Lemon’s apartment. Viewers will also see Alec Baldwin’s character Jack Donaghy’s office, which is decorated with photo mock-ups of his character with celebrities. The show airs today at 8:30 a.m.
