This is a photomechanical print (PMT) originally from the archive of the press office of a British newspaper.
A photomechanical print is a type of print that is created through a mechanical process rather than a photographic one. This means that the image, taken from a photographic negative, is reproduced using ink on paper, typically by a printers press, rather than being developed from a photosensitive material.
Photomechanical prints were developed to meet various needs, such as providing a practical and economical method for mass reproduction, allowing for the simultaneous printing of images with text, and increasing the permanence and perceived objectivity of images. Oddly less of these seem to have survived compared to photographs. They generally have a newsworthy text with them and can be more valuable than photographs as they are generally not reproduced.
These prints are common in many settings, including museums, libraries, archives, and personal collections. They exist at the intersection of photography and printmaking, combining elements of both disciplines
