An archive of 11 photographs from Captain Scott's Terra Nova expedition (1910-1912) to the South Pole is to auction at Christie's London with a ?�20,000-30,000 ($29,537-44,305) estimate.
It's set to provide one of the highlights of the Around the World auction on April 28, which will include a fascinating selection of lots from various countries.
Christie's explains: "This set of photographs are copies of unique photographs taken by Scott himself, documenting the building of the expeditions base hut, the winter on Ross Island and the long, fateful summer's march to towards the South Pole.
"The negatives and camera survived, as they returned with the first relief party from the Beardmore Glacier and were developed by the expeditions photographer, Herbert Ponting, at the Ross Island hut before being shipped back to England.
"Very few were published at the time, many remained unseen and unknown, until recently."
A set of original negatives from the expedition were bought for ?�275,000 ($406,069) by the Scott Polar Research Institute (SPRI) last year.
A 34-star American civil war flag is also on offer with a valuation of ?�10,000-15,000 ($14,820-22,230).
It's believed to have been produced circa 1861-1863, shortly after Kansas entered the Union but before West Viriginia joined in June 1863.
