This image shows the outside of the Lincoln Monument complex, showing the obelisk, the statue and the bronze head exhibited outside, as well as the entrance to the tomb on the lower level.
There is no description on the back of this card.
Currently this is better known as the Lincoln Tomb, no doubt to help differentiate this structure from other monuments to Lincoln (especially the one in Washington, D.C.).
This image likely dates from the 1940s.
