U.S.A. ★★/★/⊙. Extensive cinderella/Christmas seals, housed on a thick stack of quadrille album leaves, including progressive colour trials, some surprisingly interesting postal history, well written up, imperfs, general collateral, etc. All this is from the early 20th century onwards, including much unlisted in the general catalogues. A collection that deserves considerable study and research, much more here than this outlined description. Please inspect, you will not be disappointed.
