These two pairs of bookends are from Germany, and are unusual because they sport celluloid parts. The mariners are of painted spelter set on marble bases and have celluloid hands and faces. The celebrating cabaret performers are painted spelter set on marble bases with celluloid arms, legs and chests, and hold celluloid cups in their celluloid hands.
In the U.S., bookends with celluloid parts were produced chiefly by the Hirsch foundry in the early nineteen thirties, many with bakelite bases. Celluloid was used as an inexpensive substitute for ivory, but it was not considered a crude substance back then. Celluloid and bakelite were among the first plastics, they were exotic and desirable materials, and are considered collectible today.
