Pennsylvania State College - McAllister Hall - 1943:  The Pennsylvania State University (commonly referred to as Penn State and sometimes by the acronym PSU) is a public state-related land-grant research university with campuses and facilities throughout Pennsylvania. Founded in 1855 as Farmers' High School of Pennsylvania, in 1863, Penn State was named the state's first land-grant university. Its primary campus, known as Penn State University Park, is located in State College and College Township in Pennsylvania.  Centrally located between Old Main and the HUB Student Center, the McAllister Building is the home of the Department of Mathematics at Penn State. Mac Hall was constructed in 1904, and originally occupied as a men's dormitory. In 1915 it became a women's dormitory, and was later converted to an academic building. In addition to the Math Department, the McAllister Building also houses the on-campus U.S. Post Office, which is the official home of the zip code 16802 (University Park).  As a college dorm, McAllister probably never saw as much wear-and-tear as it did in its later life as a departmental and classroom building. In 2004 an $8-million renovation project was begun, and the new McAllister Building was re-opened in the summer of 2005. It now houses the Offices for Undergraduate Studies and Graduate Studies, as well as the faculty and students of the department.  This Linen Era postcard, mailed in 1943, is in good condition.  The Albertype Post Card.  Brooklyn, N.Y.  The Athletic Store, Inc.  State College, Pa.
