His extensive collection includes examples from the Colonial period through the 1890’s. Meticulously assembled, it contains most types of postal markings available for the 125-year period. such as straight-lines, territorial, fancy and unusual markings such as oval, CDS, packets, ship markings, railroad and mail route markings. It is now in the possession of the Rhode Island Historical Society.
