A very rare Thomas Edison signed photograph is being offered by University Archives in Wilton, Connecticut, with an estimate of $3,500 - $4,500.
The vintage silver gelatin photo measures 7 inches x 6 inches and is part of University Archives Rare Manuscripts, Books and Sports Memorabilia auction on 1st February,
It shows Edison seated at his desk examining one of his 1,093 patented inventions - a portable head lamp powered by a rechargable storage battery.
Edison's 'Cap Lamp' was approved by the Bureau of Mining in 1917 and used in US mines to help safety and limit deadly gas fires.
The Cap Lamp were approved by the U.S. Bureau of Mining and rolled out by 1917.
Whilst undated it is believed to be from 1923, and has been signed by Edison at the top left.
The photo has also been signed by Lewis Lueder, the official photographer to Edison.
The same photo can also be seen in the collection at The Thomas Edison National Historic Park at his Glenmont house in New Jersey.
Despite the usual paper wrinkles and a bit of foxing the photograph is in otherwise good condition, given it's age.
The provenance states the photograph originates from the historic photography collection of Dr Joseph T Pollock and is being sold with letters of authenticity from PSA and James Spence.
You can view the auction at University Archives.
