Thanks for the suggestions both!
Bill Titcombe - Looks like he did some great work for TV Comic, things like Inspector Gadget, and Willo The Wisps. These are all a little later on I think, I can see some similarities, I'm not sure.
Wally Fawkes - I think was Daily Mail and I'm pretty sure these would have been for the Polystyle Publications.
I've uploaded a couple of additional photos of art that came with the lot:
Tog - Pretty sure this is Bill Mevin - Used in a Pippin Comic ~1968
Ivor the Engine - From Playland Comic - 1968
Then there's a Tivvy - Not sure which comic this was used in, or who the artist was - 1964 ish I suspect:
Then there are these 4 which I think go together. Perhaps they are another set from Bill Mevin.
I've no idea what the series is though, or where it was used:
Anyway, I hope you enjoy looking at these. I hope I can find out a bit more about them!
