The only autograph I've ever gotten "in person" was Gerald McRaney ("Major Dad") whom I met in L.A. at an Armed Forces Television "do".
I do, however, collect autographs/signatures.
I have a nice assortment, IIDSSM (If I Do Say So Myself in internet lingo), of theater 'graphs (Sondheim, Styne, Merrill, Comden & Green, B. Cook, B. Harris, etc., etc.) movie composers (Alfred Newman, Hugo Friedhofer, Miklos Rozsa, Jerome Moross, John Williams, Jerry Goldsmith, Erich Wolfgang Korngold, etc.), lots of actors, some directors.
