Another Old Aerial Photograph of the Concordia Campus

This photograph was scanned from an old postcard by my niece Liesel Sylwester.

The photograph was done while all the old houses still were on Faculty Lane, which means before the summer of 1964. Because of the trees' foilage, only part of the Sylwester house (Faculty Lane House 01) can be seen. Can anybody date the picture more precisely?

I have uploaded the picture to this Flickr webpage. If you click on the ALL SIZES click-point and then select the ORIGINAL size, then you will see the picture in very high resolution.
