The flags are created from information that was available to me at the time and any errors are entirely mine. The sets include Union and Confederate National, Regimental, State and battle flags. Union Corps and divisional sets are also included.
These flags are drawn in a vector based drawing application and rendered to a high resolution (300 dpi) .png file. The originals were drawn to match 28mm figures (so that a Union National colour measures 30mm on the fly), but depending on the application you open the files in the images may need to be scaled.
