CJP: Well-spotted!
Freemasonry is so far off of my radar screen ... that is the second time I've posted a card with unrecognized (by me) Freemason symbology.
I think that the reason the Masons are in a mental black hole is not unlike the early google search algorithms, that is, I shun anything that often appears in proximity to the words 'conspiracy', 'conspiratorial', et al.
Q/ Is the appearance of the Freemason symbology merely a convenient pun?
Q/ Or, is the card intended to appeal to the Mason market?
Q/ Or, is the pun about the 'public square', as in:
Never kiss at the garden gate,
Love is blind, but the neighbors ain't.
I'm confident that someone contemporary to the card would have been able to better assess the card's intent.
