Keith produced his Punk Arrest series in watercolour or some similar medium and so my efforts at 'restoration' using pencils were always likely to be imperfect. The original colours have a comic-like brightness not completely ideal for raunchy subjects. It made me wonder what the images would look like in monotone so I produced some greyscale scans. The results (below) are not unpleasing.
I plan to republish the complete Punk Arrest series in greyscale like this at my mitchmen Yahoo! Group over the Christmas period (link in sidebar)
