This pressure helmet was made for "Buzz" Aldrin for use during the Apollo 11 mission in July 1969.
The Apollo pressure helmet was a transparent bubble designed to attach to the spacesuit neck ring. It was constructed of a polycarbonate shell with a red anodized aluminum neck ring, a feed port, a vent pad and duct assembly attached to the rear and a valsalva device attached to the inner ring. The valsalva device was installed so that the astronaut could "blow" his nose to prevent his ears from "popping" during the rapid ascent of launch.
There were two configurations of these pressure bubbles used on Apollo suits which were not interchangable. The style used during the Apollo missions 7 through 10 was of anodized blue aluminum, while those used from Apollo 11 through the end of the program were of anodized red aluminum.

EV Helmet:
This Extra-vehicular visor assembly was worn by astronaut Edwin "Buzz" Aldrin on the lunar surface during his historic Apollo 11 mission in July, 1969.
The A7-L Lunar Extravehicular Visor Assembly consists of a polycarbonate shell onto which the cover, visors, hinges, eyeshades, and latch are attached. It has two visors, one covered with a thermal control coating and the other with a gold optical coating. It also has two side sunshields which could be raised and lowered independently.
This helmet was worn over the pressure helmet and fastened with a latch during EVA periods, and provided impact, micrometeoroid, thermal, ultraviolet and infrared light protection.

EV Gloves:
These Extra-Vehicular (EV) gloves were made for and worn by astronaut Edwin "Buzz" Aldrin, Lunar Module Pilot of the Apollo 11 mission in July, 1969.
The gloves were constructed of an outer shell of Chromel-R fabric with thermal insulation to provide protection while handling extremely hot or cold objects. The blue fingertips were made of silicone rubber to provide sensitivity. The inner glove was of a rubber/neoprene compound, into which the restraint system was integrated, and they attached to the spacesuit using the same mechanism as the intra-vehicular gloves.

Wikipedia Article
Apollo 11 was the spaceflight which landed the first humans, Neil Armstrong and Edwin "Buzz" Aldrin, Jr, on Earth's Moon on July 20, 1969, at 20:17:39 UTC. The United States mission is considered the major accomplishment in the history of space exploration.
Launched from the Kennedy Space Center Launch Complex 39 in Merritt Island, Florida on July 16, Apollo 11 was the fifth manned mission, and the third lunar mission, of NASA's Apollo program. The crew consisted of Armstrong as Commander and Aldrin as Lunar Module Pilot, with Command Module Pilot Michael Collins. Armstrong and Aldrin landed in the Sea of Tranquility and became the first humans to walk on the Moon on July 21. Their Lunar Module, Eagle, spent 21 hours 31 minutes on the lunar surface, while Collins remained in orbit in the Command/Service Module, Columbia. The three astronauts returned to Earth on July 24, landing in the Pacific Ocean. They brought back 47.5 pounds (21.5 kg) of lunar rocks.
Apollo 11 fulfilled U.S. President John F. Kennedy's goal of reaching the Moon before the Soviet Union by the end of the 1960s, which he had expressed during a 1961 mission statement before the United States Congress: "I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth."
