Wow, I still have some Famous Monsters of Filmland mags and some rarer ones like Monster Mania and Castle of Frankentein.
I saw Christopher Lee guest star in an Avengers (Diana Rigg era) episode and he even made that into an impact part.
They are reprinting all those mags. If you have issues 1,2,or 3 of the original Famous Monsters in Fine condition or better you could get up to 500 bucks apiece for them.
