This black-and-white engraving of Charles Frederick Field, a retired detective of the Metropolitan Police Force, attributed to an 1855 issue of the “Illustrated News of the World,” features Field wearing his policeman's hat. In the image, Field sits on a chair with his torso facing slightly towards the right; the portrait captures the upper part of his torso and we can see the top part of the chair sketched in behind him. He wears a black top hat tipped back on his head as well as a version of the same clothing he would have adopted as a plainclothes detective: jacket, vest, white shirt, and cravat. A shadow behind him frames his head and adds depth to the image. The shading indicates that the hat is dark in colour but does not provide any information about the hat’s material.
