Bronze personal adornments, drawing of figures and a loop

Description

Four bronze pins are drawn in ink stippling on a cream card, set side by side, each marked with a number label. Each has an arched bow, a spring coil at one end and a long pin running along the base. Some bows have knobs or swellings along the arch, the rightmost has a lumpy, bulbous bow, and faint handwritten notes appear beneath some pieces.
