Produced in around the 1860s/ 1870s . This is a photograph on glass - not sure which production technique but possibly an Ambrotype .

Measuring approx 3 inch by 2.5 inch in a yellow  metal frame . the subject matter is of 2 ladies and girl , all dressed in their finest . Sadly the photograph glass is broken into three pieces as can be seen in the pic . The frame is a little rubbed and a little tarnished and the backing is modern card , helping keep the glass in place .
