This isn't going to help Mary very much, I'm afraid, but I think
it's very interesting:  An apartment hotel next door to our house
in a dense neighborhood of Chicago, built in the mid-1920s
with a distinctive facade, had "summer doors."

These were louvered doors that were placed like screen doors
on the outside (corridor side) of the normal doors.  You had your
residential hotel accommodation with private bath, and in the summer
the management brought these doors out of storage and put them up,
so that you could leave your regular permanent door open for air,
and still have privacy and security.

I never saw these.  In the 1980s the building was bought by a cult
and used as a commune, and the leader of the group told me
they had found one of these doors, and someone knew what they
were called.  In the 1990s the building was sold to an NPO
for conversion to a residence for the formerly homeless, or whatever,
and their architect was ruthless about discarding or destroying
everything historic about the building, while claiming and receiving
the historic tax credits.  But I digress.

The community has dozens of apartment hotels, and possibly others
had summer doors; I should ask around; but the people who own and
operate these buildings are not very community-minded and I have
not got to know many of them.
