Wilderness series by Timothy Truman

'The true story of Simon Girty'. My now grown-up kids all buy a lot of graphic novels and comics so I always have an eye out for interesting frontier style tomes and this series seems to have a bit of a cult following though I admit not to having seen them in the flesh.
I am not sure how many are in the series - I think they're all here but search the web to find out more if its your bag - certainly Truman is an accomplished comic artist and these seem a useful set to track down.
