I'm not much a fan of the superhero genre of comics, though I did enjoy them for a short while - somewhere around 1980-1984, and in that time my favourite comic was The New Teen Titans by Marv Wolfman and George Perez - I really loved it (Brother Blood! Trigon! The Brotherhood of Evil! Blackfire!).
Sometime later, in the 90s, I had a slight resurgence of interest and decided (as I then had a pay packet) to brush up my collection, which included going back to the original 1960s incarnation of the Teen Titans, and this is where I became aware of Nick Cardy's work. It was his covers that really astonished me - not only the drawing, but the composition and the design as well. To this day I have several of his covers on my wall, and I quickly added John Coates' book, The Art of Nick Cardy, to my library.
My favourite obscure Nick Cardy fact is that is that he added C3-PO and R2-D2 to Tom Jung's famous 1977 Star Wars film poster - a design later reworked by the brothers Hildebrandt. (Nick did many film posters himself, and there is also a sketchbook available of his war art).
