I predict that the Cyclorama of the Battle of Gettysburg at the Gettysburg Visitors Center will be next in line for a “facelift”. It’s a remarkable piece of art accurately depicting the battle. That won’t stop the enemies of history from defacing it (pardon the pun).
Among other things the number of figures must reflect the current demographics of the US and will need to be changed as the population distribution changes. You never imagined that of the 15,000 Confederate soldiers involved in Pickett’s charge that 1,800 of them were black and 2,000 were Hispanic, did you? Oh yes, some 300 were gay and about 80 were trangendered.
