Courtesy of Jenny, another "Name that list" challenge. What is this a list of? The answer is in extended (and on the comments page):
Luke Skywalker’s lightsaber handle, R2D2’s plastic handle, a lead cargo tag unearthed from the Jamestown colony, a stuffed teddy bear, fabric and a wooden strut piece from the Wright Flyer, a dead WWII pilot’s medal, a sheet of music from the repertoire of the Boston Symphony Orchestra (Beethoven’s “Ode to Joy”), a golf ball, a small aluminum sculpture, signatures in the form of computer codes imprinted on compact discs, badges, wedding rings, jewelry, patches, flags, medallions, coins, currency, flags, stamps, charms, pennants, postal covers, unauthorized postal covers, and unauthorized timepieces (a wristwatch and a stop watch).
Items carried into space by astronauts. See NASA.gov
