cel131 This is a superb opportunity to secure this 5" x 3.5" vintage early hand signed photo for Ivar Giaever who is a Norwegian-American engineer and physicist who shared the Nobel Prize in Physics in 1973 with Leo Esaki and Brian Josephson "for their discoveries regarding tunnelling phenomena in solids". He has personally hand signed the photo where his signature rests perfectly accompanying his portrait in mint condition. Undedicated signing too so you wont source better.
