1966 was the Summer of Pandemonia for me, searching and collecting, not just these on a daily basis, but all things Kelly. Looking at these strips now I remember the weather, the music, the other fabulous art stuff I was collecting (Frazetta comes first to mind, as his stuff also evokes the feeling of that time, tracking down the books with his art), etc etc. As I've written elsewhere 1966 was the deep end of my personal golden age (he writes with a sigh).
