A blast from the past !

Remember old photo albums?  And these corners to secure the photos?  My generation had solid colours, but these are from late 1920s to early 1930s, we figure.  Getting a start on cleaning out the garage, we discovered 2 old black paper photo albums of G's Dad.  The black paper pages are self-destructing, so to preserve the photos, we're taking them out and will scan them.  They are odd sizes and have that sheen when you look at them at an angle.   The Dad must have looked through them occasionally as some groups labeled club and graduation pictures have a separate sheet of names in his handwriting, 1919 - 1923.
Sadly, almost nothing is written on the back of the pictures.  Both parents are no longer around to ask.   Who are the people?  What stories are we missing  . . .?  We recognize so few. These belong to the previous generation.
