Cars were big back then.
Jean Hennesy is between perhaps 13 and 15 in the photo. I’d place her as being about 14 and this picture taken circa 1945.
Family gave Buddy, her brother, as being the boy in the photo but Buddy is 3 years younger than Jean and there appears to be a much greater age difference between Jean and the boy than 3 years.
The photo would have been taken in Mobile, Alabama.
