Dr. Whitney Smith Jr. was an American professional vexillologist (a scholar of the history of flags and banners) and political scientist. He coined the term vexillology, which refers to the scholarly analysis of flags and banners in all aspects.
I believe I got this on a field trip to Philadelphia in 1976 for the Bicentennial. If it was indeed then, I wore a Revolutionary War outfit that day and was on the channel 6 news. :)
Each of our nation's early flags is presented with the history of the flag. The outlines of the flag are presented for one to color, if he chooses.
