Fictional Fans

Late 60s, The Jungle Books by Kipling, age 8, quickly followed in the next few years by Star Trek on the black and white TV and ACD's Sherlock Holmes and The Hobbit and The Lord of the Rings.

"Cos"play (acting out characters, wearing things symbolic of the characters) and stories in my head mostly.

Mid 70s, my first experience of sharing fandom with others was in high school, my gfs and I wrote fanfic about our favorite band.
