My trade-mark consists of a facsimile signature of the firm of "Fratelli Branca e Co." which may be printed or otherwise produced upon or applied to the packages containing the medicinal preparations. As shown in the drawing the signature appears upon a small oblong label having a ground work of elliptical spaces within each of which appears the words, "Fernet, Branca, Fernet, Branca", usually printed in yellow ink on white paper and inclosed by a black border and the fac simile signature "Fratelli Branca e Co." lithographed in black ink over such groundwork, lengthwise of the label. The size and appearance of label, may be varied at pleasure, without affecting the character of my trade-mark, the essential feature of which is the fac simile signature, "FRATELLI BRANCA E CO.".
