This is a rare view of Pennsylvania College taken from North Washington and Railroad Streets.  On the reverse, is the photographer: Tyson Brothers, Gettysburg, Pennsylvania.  The clarity and sharpness of this CDV is excellent and is quite amazing when enlarged!  According to the book Early Photography at Gettysburg, pg 108, the Tyson Brothers most likely took this shot about April 1862.  The corners on the CDV have been rounded and the reverse reveals one bend (not affecting the image).  A rare photo for the Gettysburg collector!
