Whether anti-masonic or not, I'm wondering if it isn't of some sort of French decent...
The covering over what looks to be the "master" has the abreviation A.L.G.D.G.A.D.U., which according to Mackey's Encylcopedia of Freemasonry is A la Glore du Grand Architecte del' Univers... Translated to English is "To the Glory of the Grand Achitect of the Universe". Mackey said it was the usual caption of French Masonic documents.
Also, the banner behind the hooded person on the left has the abbreviation G.E., which Mackey alo says to be either Grand Encampment or Grand East.
In the center of the picture, up at the ceiling is a doubleheaded eagle. Scottish Rite has a lot of history coming from France. Though, I see other things that could link to other SR stuff, and also YR stuff.
Whether regular or irregular, Masonic or anti-masonic, possibly the source of this potentially be French or some place that has strong French roots???
