This is a set of 4 different commemorative plates commissioned by MIT from Wedgwood in 1952.  These plates are based on the engravings of Samuel Chamberlain (MIT Class of 1918) and were issued in a limited edition of 250 sets.  This set for sale includes Dupont Court (154/250), Building Ten (154/250), Charles Hayden Memorial Library (154/250), and Baker House (154/250).  Each plate is in sepia with a cream color border and a gold edge and measures 10.75 inches in diameter.  No cracks or chips.  No crazing.  The gold trim is intact with rare scratches.  I will pack carefully for shipping.  Thanks for looking at this listing.
