Bridgeport Fireman, Waterbury, Connecticut, Rohloff E-6, bold, somewhat worn impression ties 1861 3c rose to cover to Saugatuck, Connecticut, Watebury c.d.s. (7 May) alongside, a clean and fresh cover, with slight adhesive residue on reverse, stamp with small piece torn at upper left, cancellation extensively enhanced, yet a visually-pleasing example of this ever-popular cancellation, signed Dr. Jackson, but omitted from his 1970 R.A. Siegel sale; with 2020 Philatelic Foundation certificate.
Provenance:
Dr. Glenn Jackson (Private Transaction)
Paul C. Rohloff (Private Transaction)
Gordon Eubanks (Private Transaction)
John R. Boker Jr. (Private Transaction)
Rohloff records no more than eight covers known of this highly recognizable design. While this certainly underestimates the true number of examples extant,  it remains one of the most popular and desirable of all United States fancy cancels.
