This is a vintage black and white photograph featuring two men holding a large, geometric structure. The structure is triangular in overall shape and composed of numerous smaller, dark triangles connected by a grid of lighter lines. It appears to be a model or prototype of some kind. The two men are dressed in suits, typical of the early 20th century. They are standing on a grassy area, likely a park or campus, with trees and a building visible in the background. The men are holding the structure horizontally, each supporting one side. The image has a slightly grainy texture, consistent with older photography. The overall composition is formal and suggests a scientific or engineering context.
