This picture postcard of the lobby of the U.S. Grant Hotel in San Diego carries a logo of the Panama-California Exposition of 1915 on the message side, suggesting its distribution and use during that event. In 2020 this hotel is known as The US Grant and is listed on the National Register of Historic Places. The architect was Harrison Albright (1866-1933), and it had just opened in 1910, when this photograph was taken. The Curt Teich number on the back has been decoded to 1910.
