This image shows the bed and associated furniture used by one of the daughters of the Rowan family in the building known as My Old Kentucky Home.
The description states:
The Girls’ Room
MY OLD KENTUCKY HOME
–This bed appears to be even wider than the one used by the mother in the previous posting, and includes a trundle bed shown emerging underneath the foot of the larger bed. Such beds were commonly used for younger siblings.
This image likely dates from the 1950s.
