3 color silkscreen. from my 6L series. funny story- I was trying to put a '79' on the back of a book I was making and I put it upside down, so it looked like 6L - I just went with it. so after that book, I started making other illustrations and just marking them with a 6L and a date code to give me nice random excuse to use some type. moral of the story, learn to roll with the punches. especially punches you throw at yourself.
