This lot consists of three thermoplastic cases with ambrotypes. The first case is black with Kinsley and Parker exterior hinges. The image is a sixteenth plate, and the embossed covers are decorated with an oval and border reminiscent of the entrance to a mausoleum; the motif is repeated on front and back. The amber velvet lining has light wear, and the Kinsley and Parker hinges are difficult to find on a case like this. The case has a snug clasp. There are slight chips at two corners on the back, and the case measures 2 1/8 x 1 7/8 in. wide. Kinsley and Parker were located in Stoughton, Mass. and were granted a patent for these hinges in 1858. The round hinges were designed to provide less strain and a stronger connection between the front and back covers of thermoplastic cases from this time period. The second case features an ambrotype of a gentleman wearing a suit, vest, and dark bowtie. The ambrotype is a ninth plate, and the embossed covers feature a simple geometric pattern that is repeated on front and back. The velvet lining is soft and pliable, and the case has a snug clasp. The case was probably made in the 1850’s and measures 3 x 2 5/8 in. wide. The third case shows an ambrotype of a woman in a thin-waisted dress and a fancy hat. The ambrotype is a ninth plate, and the embossed covers feature a decorative motif that is repeated on front and back. The velvet lining has wear and the covers have tiny nicks along the edges. The case has a snug clasp and was probably made in the 1850’s, and it measures 3 x 2 1/2 in. wide.
