Non-sports autograph collectors- how do you collect?

[boadster]

I stick to the key cards, and if I think there is potential, I buy multiples and just put them away for my 2 boys. For instance, I have 13 Robert Downey Jr Iron Man cards from Rittenhouse and 6 Chris Pratt GOTG autographed cards. Yes, I also get them all graded as well...I am also starting to focus on costume/ auto cards or dual auto cards...Methodology is more in line to what the sportscard side does...
