An adult male with dark skin is engaged in masonry work at a construction site in Karsana 2, Nigeria. He is wearing a light blue long-sleeved shirt, light-colored trousers, light sandals, and a patterned knit cap. The individual is bent over, using a small trowel in his right hand to apply a pile of brownish-grey mortar onto a partially constructed wall made of grey hollow-core concrete blocks. A vertical stack of similar concrete blocks is positioned to his left. The ground immediately surrounding the work area is a light-colored, hardened surface with scattered dirt and mortar. In the background, a vast, undeveloped landscape features green and brown vegetation, additional partially constructed block walls, and a curving reddish-brown dirt road with a distant vehicle. Hazy blue-grey hills are visible on the horizon under a clear, bright sky.
