This link takes you to a picture from that time: http://digitallibrary.usc.edu/search/controller/view/impa-m9215.html
Click on the picture to enlarge it. You can save it if you don't
have it by right clicking, save as.... You have to print the info
separately although I am not sure it is accurate.
Another picture from the same time frame and same source as above. http://digitallibrary.usc.edu/search/controller/view/impa-m9215.html
Another picture from the same source. Uncle Ralph is credited as photographer but I can't tell if he is in it. http://digitallibrary.usc.edu/search/controller/view/impa-m5764.html
Got around to doing another search for
Ralph in the Yale archives. Ralph apparently donated 130 b&w
photographs which are indexed here.
They are in very good condition, mostly. I might have a vague memory of
Ralph having glass slides at one time, which might be the media used
here. There are rough dates.
It’s interesting—the info from Beth has
links to the USC library, which seems to have four photos. USC credits
Yale as the source and Ralph as photographer but somehow has much more detailed
information (i.e., names of the people in the photos.)
Ralph's picture of a bride on the way to her wedding has been saved a couple times with commentary.
