I was a child of the 60's, when the UK comic scene was quite healthy, thank you very much, not like now ...
I was also quite spoiled. I didn't get any pocket money but I got just about every UK comic coming out at the time.
I also got into American comics and I am pretty sure at one time I had a very early issue of the Fantastic Four (somewhere below issue 5).
Anyhow : UK comics in the 60's. We had DC Thompson : Beano, Dandy, Beezer, Topper ... later on, the Sparky.
Rover, Hotspur, Hornet, Victor. I even read my sister's comics, such as the Bunty and the Judy.
We had IPC/Fleetway/Odhams : Lion, Tiger, Valiant. Buster, Whizzer and Chips. The Big One. Wham, Pow, Smash. Fantastic, Terrific.
TV 21, TV Comic, TV Tornado. Joe 90 : Top Secret.
I'm sure I'm missing some : but being a child of the 60's I'm old and the memory isn't what it once was. However, I still buy and read American comics to this day. I was imbued with a love for comics that still hasn't died. It is a source of sadness for me that the UK comic market that was so healthy in the early 60's has all but died. Even in my youth, I remember comics merging left right and centre; it was already the beginning of the end.
