The image shows a black helmet with a metal spike on top of it, placed on a surface with a scale beside it. The helmet is a pickelhaube, a type of helmet worn by a German soldier during World War I. It is made of metal and has a spiky top, with a wide brim and a crest on the front. The scale beside the helmet is likely used to measure the size of the helmet.
