Nowadays I can say I have heard the contents of most of these records. Some still stand up as chilling or evocative today.
I never saw that Blazing Combat mag. I always figured that the implied competition between Uncle Creepy and Cousin Eerie was an attempt to make fans buy both and compare 'em.
Pow! Zam! I might have read an issue or two of Screen Thrills, but I bet a lot of the "thrills" have leaked out of these properties over time.
See you Monday!
