The trade-mark consists of a rectangular-framed label bearing in its center the Portuguese coat of arms standing upon a pedestal. Above this coat of arms is placed a crown. On one side of this coat of arms a woman with gloriole is leaning with her right arm upon the coat of arms and carries in her left hand a vine-grape. On the other side of the coat of arms lies a dragon with spread wings. At the top of the label is arranged a ribbon-like band with the inscription "Real Companhia dos Vinhos do Porto", all in capital letters; but the rectangular border-line and the flying ribbon may be omitted entirely. The essential features of this trade-mark are the symbol of a shield surmounted by a crown with a woman holding a bunch of grapes at the right side and a dragon couchant regardant at the other side of said shield.
