Found in The Sunday School Helper, Northwestern Universalist Publishing House, 1882:
Explanation.- The “Monogram” can be made of thin pieces of board, and attached to a stand, or small boxes of different sizes, as exhibited in the above illustration. But the better and perhaps the cheaper way for schools will be to order the monograms from the Publishing House, where a sample can be seen. They are made of metal and wire and painted green, and can be appropriately used for church decoration at any time. The prices of the monograms will be as follows: Three and one quarter feet in height $1.00/ Four and one half feet high $1.15. Orders for monograms should be sent in March.
Apparently, the above decoration was intended completely without irony.
We looked over for this for several minutes before I noted the title, and probably we would have discovered the real meaning sooner, except I was the only person who could see said title because of the angle of my computer screen:
JESUS HOMINUM SALVATOR
IT’S intended to be JHS- the cross is the j- not a dollar sign superimposed over the cross.
