Etchings
Etchings are produced, usually but not always in a monochrome image, acid cut into a zinc panel, most often for historical and ecological sites interpretation.
The examples shown here explain the past, 'how the coal mine used to look and function at its peak' 'the formation of coal' and 'what the mine has become for wildlife since restoration'. Interpretation panels usually include an amount of text, titling, logos, and other graphics.
