Original antique advertising circular from Sears, Roebuck and Co. of Chicago, promoting a free $2.50 acetylene bicycle lamp with the purchase of a Sears Elgin King or Elgin Queen bicycle at their special $18.00 price. Printed sheet includes a detailed engraved illustration of the brass, nickel-plated acetylene lamp along with full descriptive copy on its construction and use, plus Sears' order instructions and their "Cheapest Supply House on Earth" tagline. Numbered "114H" in the upper corner. Single sheet, folded once with two mailing-style creases; the reverse is plain with light bleed-through from the front printing. Genuine piece of early bicycle/Sears advertising ephemera, great for a cycling collector or vintage advertising display. AS IS — please examine all photos for actual condition; expected wear consistent with age includes fold creases, a couple small edge tears/soft corners, and light toning.
