IF YOU ARE A COLLECTOR OF CROSBY FIRST DAY COVERS AND YOU DO NOT OWN KENNETH M. STERN’S FIVE VOLUMES FEATURING CROSBY FDC’S EXCLUSIVELY, YOU SHOULD PURCHASE IT. 

WITH OVER 2,500 UNIQUE VARIATIONS THAT ARE NOT IN PLANTY/MELLONE, THESE FIVE VOLUMES FULLY IN COLOR ARE PRICELESS.

I HAVE NO AFFILIATION WITH MR. STERN, BUT AM GRATEFUL TO HIM FOR PRODUCING THESE MASTERPIECE VOLUMES WHICH HAVE ENHANCED MY COLLECTING PLEASURE SO GREATLY.
