I'm obsessed with big time rush and the vampire diaries im trying to get everyone that guest starred on both shows and the main characters

I've been trying to assemble a complete set of autographs from The Sopranos, including main cast members, co stars, featured players, and even notable guest appearances. Its quite a task and while i have gotten quite a few, i still have at LEAST 50 people to get, and i havent even included directors or writers....but i DID get David Chase!

Has anyone started a huge project of getting the autographs of a certain kind?

I have been working for the last 20 years on getting the whole 1991 Topps baseball card set signed. So far I've gotten over 800 of the 924 cards signed. Every other year I buy another unsigned set and send out to all that I don't have, and get another handful back.
