A structural worker bolts beams on the framework during the construction of the Empire State Building in New York City. The 1,250-foot (380 m) building opened on May 1, 1931, at the time the tallest building in the world, overtaking the Chrysler Building (seen to the right), which had just been completed the year before. The addition of a pinnacle and antennas later increased its overall height to 1,472 feet (449 m).

The Hispano Aviación HA-1112 was a license-built version of the Messerschmitt Bf 109G-2 developed in Spain during and after World War II. The Spanish government in 1942 contracted with Messerschmitt to supply Bf 109G-2 materials, but due to difficulties incurred by the war, the company only delivered 25 incomplete airframes to Hispano Aviación. The plane shown in this photo has been rebuilt to resemble a Luftwaffe Bf 109, except without the Nazi swastika.

Another act of military surrender was signed, shortly before midnight, on 8 May in the outskirts of Berlin, Germany, at the insistence of the Soviets.

A film, reenacting supposed Spanish atrocities in Cuba, one of many pieces of propaganda of the Spanish–American War. American newspapers ran stories of a sensationalist nature, often without confirming facts; this type of journalism became known as yellow journalism, which helped to precipitate military action by the U.S.

Archaeological and paleontological excavations at the site of Gran Dolina, in the Atapuerca Mountains of Spain, where fossils and stone tools of the earliest known hominians in Western Europe have been found. Two archaeological levels are visible in this shot: The first one is TD-10, and it is believed to be a Homo heidelbergensis camp, about 300,000 years old. The second is TD-6, located under the scaffolding (bottom centre). The first remains of the new species mentioned by the Atapuerca team, Homo antecessor, were found there, about 800,000 years old.

A ca. 1850 Japanese woodblock print of Somagahana Fuchiemon, a sumo wrestler. The Japanese tradition of sumo is an ancient one, having originally been associated with the Shinto religion. Over time it evolved into a form of wrestling combat, and then into a sport. Most of the current rules of the sport developed in the early Edo period. Current professional sumo tournaments began in the Tomioka Hachiman Shrine in 1684, and then were held in the Ekō-in in the Edo period. They have been held in the Ryōgoku Kokugikan since 1909.
