Consistent with a pen of this age, there is some wear to the gold plating on the clip and cap bands. The celluloid (or hard rubber) body shows some surface oxidation (fading), but the mottled orange/black pattern remains striking. The nib shows minor age-related patina.

Note: This is a "Security" self-filling model, patented May 4, 1920. It is a rare piece of Chicago writing history.
