Mailed advertising materials offering a free trial of Palmo Globules to "sufferer(s) of those most common and distressing symptoms of so-called Bladder Weakness, Urethral Irritations or Prostate Trouble." In original mailing envelope postmarked Feb. 23, 1927. Printed letter explaining the unusual opportunity to try a much praised treatment without cost," with a graphic of the box in lower corner; coupon postcard with photo of a man (presumably H. D. Powers) in the corner; self-addressed return envelope and a smaller "Free Proof Coupon" envelope for enclosing a dime and attesting "I have never used them before."

Cited for false advertising by the FTC, per the 1932 Annual Report: "Harry D. Powers, trading as Palmo Co., Battle Creek; Mich., a distributor of “Palmo Globules,” an alleged cure for bladder trouble, cystitis, and general debility, agrees to discontinue representing that any definite proportion of men are afflicted with prostatic trouble, unless such representation is based upon authentic information; to discontinue representing that the treatment will cause the user to sleep all night, without a qualifying statement to the effect that this is true only when the sleeplessness is due to bladder and urinary irritation; and to discontinue representing that the preparation will produce a soothing or healing action that will convince the most skeptical, when such is not the fact."
