Korean [Chinese] Twins on French Double-Sided Sample Pitchcard

Two Sided French pitchcard for the Chinese Twins, printed on thick coverstock, probably used as a sample piece to pitch the actual cards that were sold at the show. A set of two signs advertising the twins were purchased together with this double-sided pitchcard. My theory is that the two signs and sample card were kept together by a European exhibitor of the twins....... Translated from the French: "The Chinese Twins. LIU SOON SAN and LIU TANG SAN, are forced by a remarkable play of nature, to spend their lives inexorably riveted to each other; as was the case with conjoined twins.
