Update to A Missionary Mystery (facts prove useful)

In the order in which they appeared, here’s the help my friends gave me:

from my friend since 2002, Foxy J:

Looks like it pertains to the earlier time period, based on the information here that talks about when the Missionary Home was at that address. The description of activities at the Missionary Home in the 1920s seems to fit.

However, I still wonder about the reference to the "Church Office Building" because that wasn't dedicated to the early 1970s, and I can't find another administrative building referred to by that name during earlier times.

from Kent, the creator of one of my favorites, Mormon Baseball:

I'm fairly sure that the "Church Office Building" was what is now called the "Church Administration Building", built in 1917

from El, who has been taking apart an erstwhile favorite of mine, the clincher:

okay, here's my best guess

• The main title font is Coronet, which was created in 1937.

• I'm less confident on the "MISSIONARY HOME" font, but my current best guess is Erbar, created in 1926 (It's such a small sample size that I can't be certain)

• The font for the bulk of the text is, I believe, Dutch Mediaeval, created in 1912

• The end of the YWMIA was hardest to find--I ended up looking at "sustainings of General authorities" from past conferences. October 1973 had the sustaining of the YWMIA general board. April 1974 has a solemn assembly (for Kimball), and it's the "Aaronic Priesthood MIA (YW)." (There's also an Ensign article from January 1973 about the MIA program that makes things a little less clear as well https://www.churchofjesuschrist.org/study/ensign/1973/01/news-of-the-church/first-presidency-announces-priesthood-mia-programs?lang=eng)

• Based on some comments in the Improvement Era, it does look like Kent's suggestion of the Church Administration Building being referred to as the "Church Office Building" is accurate (there's a reference in 1963 that definitely isn't referring to the newer building)

• An IE article mentions the Lion House Cafeteria closing "for an indefinite period of time" in March of 1964 (April 1964 IE, p. 292)

• Based on a chapter from Richard Cowan, the Missionary Home was used until March of 1962 (when it was moved into a hotel)

• Smallpox vaccination requirements could have been as early as the 1800s (I haven't found a source specifying things for missionaries yet), while typhoid vaccination was required for the US Army in 1911

• usage of "Temple Block" in the IE appears to taper off in the mid-1960s

• The Bureau of information started in 1904

• Commercial flights in SLC began in 1926, with major improvements to the airport in 1933 and 1950

So, as of this point, it's between 1937 (Coronet's creation) and 1962. I'd guess it's from your grandma based on the age.
