Cover from a "getting ready for General Convention 1915" newsletter. On the special train that took delegates to California!
But where does the name come from? My guess:
- UGC: Universalist General Convention
- WUMA: Women’s Universalist Missionary Association (I’m guessing. The organization tended to change names. A precursor to the UU Women's Federation.)
- YPCU: Young People’s Christian Union
- SS: probably Sunday School (Union)
