This is unique as a ‘set’, missing only the 90c value (Scott 111), which is not known to exist in block form. Of the nine values represented, six are unique as blocks. These blocks were in the Caspary, Lilly, Heatherington, and Whitman collections, elevating the status of the collections as their philatelic stature was equally elevated by their place in such prestigious collections! Sonny originally purchased these blocks privately on behalf of a West Coast collector and later advised Alan Whitman to purchase them as a foundation in forming his now famous collection of United States Blocks. When sold, it realized over $900,000! It now resides in the William Gross Collection.
