Sold by all dealers. Twenty years later, when the Civil War had passed out of recent memory and Confederate currency was presumably becoming a curiosity, Comstock printed facsimiles of $20 Confederate bills,[9] with testimonials and advertisements upon the reverse side; it can be assumed that these had enough historical interest to circulate widely and attract attention, although each possessor must have felt a twinge of disappointment upon realizing that his bill was not genuine but merely an advertising gimmick. [Footnote 9: These facsimile bills were registered as a trademark at the United States Patent Office. In his registration application, Mr. Comstock described himself as a citizen of the United States, residing at Morristown, N.Y.--although he had served three terms as mayor of Brockville, Ontario, prior to this time.] Back in the 1850s, the Comstock Company in lower Manhattan had an advertising agent, one Silas B. Force, whose correspondence by some unexplained happenstance was also deposited in the loft of the Indian Root Pill building in Morristown, even though he was not an exclusive agent and served other clients besides the Comstocks. One of these was Dr. Uncas Brant, for whom Force had the following announcement printed in numerous papers: AN OLD INDIAN DOCTOR WHO HAD made his fortune and retired from business, will spend the remainder of his days in curing that dreadful disease--CONSUMPTION--FREE OF CHARGE: his earnest desire being to communicate to the world his remedies that have proved successful in more than 3,000 cases. He requires each applicant to send him a minute description of the symptoms, with two Stamps (6 cts) to pay the return letter, in which he will return his _advice prescription_, with directions for preparing the medicines &c. _The Old Doctor_ hopes that those afflicted will not, on account of delicacy, refrain from consulting him because he makes _No Charge_. His sole object in advertising is to do all the good he can, before he dies. He feels that he is justly celebrated for cure of Consumption, Asthma, Bronchitis, Nervous Affections, Coughs, Colds, &c.
