Offered via a 1916 promotion by The Sporting News, M101-4's are blank backed and feature the well-known Felix Mendelsohn images that launched several issues in the World War 1 era. This PSA 2 has the aforementioned back looking good, with some uneven, light toning and spot of foxing.  The obverse is, unfortunately, not a match and some significant paper and image loss is seen at the upper right of this PSA 2 example.
