It may have been put out by an entrepreneur back then as this post on a different forum mentions:
Quote:Until 1883, the GAR National Encampments did not have delegates' badges or ribbons. However,
they spawned a variety of badges and ribbons for those who attended. At the top of the pile is the delegate's badge, for those sent to the encampment as voting members. In this case, the 1882 national encampment in Baltimore had only 227 delegates attend.
Because many GAR members who were not accredited as delegates attended, they wanted something to show that they had been there, so the entrepreneurs of the day started cranking out souvenir badges for purchase. The GAR, seeing another source of funds, quickly joined in and contracted for "official souvenir" badges.
Many of the departments, and a fair number of posts, had their own badges or ribbons made up for the national encampments. Most of these are relatively simple, but some got rather gaudy. (post #12
