With the last zoom in, this time into the North Visitor’s Center, the image features the Christus statue.
Intermountain Tourist Supply, Inc. Salt Lake City 1, Utah
This is not an original, but a copy based on a work by a Danish sculptor, as indicated in the description:
THE CHRISTUS by Berthold Thorvaldsen, TEMPLE SQUARE VISITOR CENTER, SALT LAKE CITY, UTAH. This impressive statue is located in the rotunda of the Visitor Center on Temple Square.
The postcard dates from the 1960s.
