I am currently busy with boring day jobs and smugly secret drawing jobs so he's some I did earlier.
In 1995/6 I filled up an A5 Seawhite sketchbook with a cowboy story, entirely drawn in brown pilot pen (3 or 5).
It was a Cowboy Treasure story that simply wandered off into a sketchbook of loads of wild west characters mucking about.
I saw it in the loft today when i was putting the tent away.
Might post some more, maybe have another go at the adventure.
