Hi there!
This is indeed a Wisconsin unit... The Second Wisconsin Volunteer Infantry on the first day at Gettysburg.
I am already at work on the second series of sets for this series.
We chose this painting to re create in full round figures to add to the Iron Brigade figures already released.
With these special licensed figures and our own designs you will be able to build a diorama looking very much like Keith's painting.
The base features our Hudson & Allen 'Wild Grass' and also includes a backdrop printed with archival quality paper and inks. It was created with Keith's permission to help the collector reproduce the entire action as depicted in the original painting. As far as I know this approach is a first for historical miniature sets based on licensed art from well known artists.
Hope this helps!
Ken Osen
