We have pretty much all of the research done now - but Devereaux is an super busy lawyer here in Tennessee. We have not chatted about it in a year or so pending the completion of the research.
We are also considering expanding it to cover all three national flags and have the work done for those already too should we go that route.
It will be heavily illustrated and thus not a cheap book price-wise. We have a publisher already.
Let me see what Deveraux has on his plate.
