This is the first of two 16mm rolls that have survived quite well.
This is from around 1922 and shows Edward Donald Moisant and Mary Adelaide
(Longtin) Moisant (Nannie's parents), Nannie and her husband Alfred Waldemar Malcolmson,
her sister Harriet Rosanna Moisant (Aunt Hattie to the Povey's), Hattie's son Edward Rogers Grey,
and Nannie's son (the toddler) Alfred Waldemar Malcolmson Jr.
Bert Moisant enters and lays on the grass at one point - apparently Alfred Sr. exits to operate the camera.
Bert is clearly directing the scene, as everyone does a good job of acting casual and reading magazines. The location is likely Los Angeles.
