Brillendoos van doorzichtige materiaal met de opdruk 'J.H. GROENINK Mr. Opticien Optische slijperij Sarphatistraat 52 / Tel. 51079 / Amsterdam C' c. 1920

This clear plastic case, created by Fa. J.H. Groenink circa 1920, served as a container for eyeglasses. It's an example of early 20th-century Dutch advertising, featuring the optician's name, address, and phone number. The case's simple design reflects the practicality of the period, while the green printing adds a subtle visual interest. These cases, once commonplace, are now considered ephemera, offering a glimpse into the past.
