A German porcelain mustache cup featuring a hand-painted and relief-molded exterior. The vessel body displays a shaded ground that transitions from light green at the rim to a pale blue towards the base. A large cobalt blue crescent panel is positioned at the upper front, embellished with gilded floral sprays. The body is heavily adorned with high-relief applied porcelain flowers in shades of orange and white, accompanied by dark blue and green leaf motifs. The interior features a fixed porcelain bridge with a gilded edge, designed to serve as a mustache guard. The piece has a simple loop handle finished in a pale blue glaze. The underside of the base bears a printed mark in dark ink consisting of a crown above a shield-shaped crest containing the letters R and S, with the word GERMANY printed in an arc below. A hand-painted number 67 in dark pigment is visible adjacent to the printed mark.
