by our rough approximation about 4,000 covers ranging from the early 1920s through World War II, sorted by issue with numerous event covers interspersed chronologically, highlights too numerous to mention but the early binders alone include 551 and 576 combination (7), 555 (4 Hodgenville, Scott $350 each), 557 (8 including 3 New York), 558 (2), 559 (7 including 2 Niles), 560 (3), 561 (4), 562 (4), 563, 564 (4 Washington, 4 Caldwell, 3 Boston), 565 (3 Washington, Scott $400 each, plus Muskogee with APEX certificate, Scott $1,250), 566 (Scott $575), 567 (Scott $600), 568 (Scott $650), 569 ($800), 570 (Scott $1,500), 606, 612 (4), 614-16 (19, various cities), 617-19 (17 including Washington, Cambridge, Concord, Lexington, Boston, and Lynn), 620-21 (20), 622 (13 including two North Bend, Scott $200 each), 623 (20), 692 (2), 693 (4), 694 (4), 695 (3), 696 (2), 698 (5, Scott $300 each), 699 (Scott $350), 700 (3, Scott $300 each), 701 (Scott $400), C4, C5, C6, C7 (8), C8 (4), C9 (15), E12 (Scott $500), E13 (2, Scott $400 each), E14 (2), E15 (5), E16 (2), QE1, QE2, QE3, and QE4, better later covers including Prexies complete to the $5, variety of different cachets for each issue (including hand-painted and first cachets), generally very fine with covers selected for their eye-appeal, an incredible holding which would take ages to duplicate, ideal for continuation or resale, difficult to do this lot justice in words but we are confident the buyer will not be disappointed
