These seem to all be from the same roll and one said it was in Uncle Charlie's front yard with EAF's 1949 Mercury.
Since these were my great grandmother's (Jesse Blanche Brown Nelson) pictures,
I think Uncle Charlie is her husband's uncle Charles M Nelson b Nov 1880 in Arkansas and living in Lonoke in 1930.
His five kids included Eurice 1906, Valerie 1908, Carl M 29 Jul 1909, Naomi 1913 & Bernice 1920.
These could be Uncle Charlie's kids around 1950.
Great Grandma's address book listed a Carl Nelson in England, Arkansas (still Lonoke Co).
