This is an image of the existing Arts and Sciences Building on the campus of the University of Wyoming at Laramie.

There is no caption on the back of this card. The inscription at the bottom states:
Liberal Arts Building – University of Wyoming – Laramie Wyo. / Sanborn Y-1996

The building was started in the late 1930s and is still used for the same purpose today, though the name has been updated to more typical usage. The Arts and Sciences Building is listed on a tour of historic sites on the campus, and the link above lists it as item number 10.

This image likely dates from the 1940s.
