Three pen-and-ink architectural drawings on brown kraft paper are arranged overlapping on a light-colored wooden surface. The most prominent drawing, located at the bottom left, depicts the Etchmiadzin Cathedral in Vagharshapat, Armenia. This detailed sketch showcases a multi-tiered bell tower with a prominent central dome, flanked by two smaller domes/towers, and featuring arched entrances, multiple windows, and balconies with railings. A clock face is visible on one section of the structure. The sky above includes stylized clouds and a flock of small, silhouetted birds in flight. Overlapping the top right portion of the Etchmiadzin drawing is a second sketch, oriented diagonally, showing a European Gothic-style cathedral. This drawing features a tall, slender spire, pointed arches, intricate tracery, and flying buttresses. Scribbled lines represent clouds in the background. A third, mostly obscured drawing is visible at the top left, beneath the Gothic cathedral sketch. It depicts the upper portion of a building characterized by a distinct pointed, multi-tiered spire and associated roofline. A clear plastic ruler with black numerical markings is partially visible along the bottom right edge of the wooden surface. The overall lighting suggests an indoor setting, possibly under artificial light.
