This is pretty cool — Patrick Mansell, Penn State’s news and relations photographer, photoshopped images of Penn State’s yesteryear with today’s images to show just how different campus life was back then.

You’re bored right now, so check it out:

Joseph Garratti roughs out the front leg of the Lion Shrine in 1942, the year the Class of 1940’s class gift was completed.

Allen Street used to run unencumbered through campus, as you can see on the left image from 1924.

Now, the basement of Old Main houses university development. Then, it housed the Old Main Sandwich Shop.

The Agriculture Experiment Station was the first agriculture building on campus, pictured on the left in 1889. It’s been renovated several times since, but President George Atherton’s brainchild still stands near the Armsby Building.

There are some non-photoshopped images of Penn State’s past as well that are still fun to look at. In this one, Penn State students leave morning chapel services and head to Ag Hill in 1913. That’s pre-reconstruction Old Main in the background, with the site of the Davey Laboratory on the left.

Communications majors will especially appreciate this photo of the Carnegie Building’s construction in 1904.

All of the images can be found here.
