This image shows the memorial cenotaph that sits above the tomb of Abraham Lincoln, the 16th President of the United States.
Genuine Curteich-Chicago “C.T. Art Colortone”
The description states:
Two feet back of this cenotaph and ten feet below the floor lies the immortal Lincoln. The flags shown in the background represent the states where the life of the Lincoln generations have lived. In addition to the body of Lincoln, the monument contains the bodies of Mrs.Lincoln and three of the four Lincoln children.
–The room visible here was redecorated in this style in 1931, but has changed little in the intervening decades.
This image likely dates from the 1940s.
