We've already reported on the unusual tool of espionage featured in Waddington's forthcoming 20th Century Design auction, on March 31.
A "pointing scope" possibly used to spy on the US from a Russian Military space station will go under the hammer with an estimate of $8,000-10,000.
But perhaps even more remarkable is the appearance of a flown Sokol KV-2 Space Suit, worn in space by cosmonaut Anatoli Pavlovich Artsebarsky.
Initially developed in 1973 by NPP Zvedza, the Sokol space suit was an incredible piece of design and is still used in today's cosmonaut missions.
The suit was designed for protection from cabin depressurisation during launch and re-entry, and can be worn for short periods in open space.
In 1991, Artsebarsky spent 145 days as commander of the Soyuz TM-12/MIR-9 mission (from May 18 to October 10) logging a total of 33 hours of space walking.
Interested collectors will be able to get a closer look at the suit's various gizmos - including a secondary interior communications hood and pressure equalisation valve - when it and the sale's other lots are exhibited between March 28-30 at Waddington's in Canada.
Artsebarsky's suit carries a sky-high estimate of $25,000-£35,000.
Another Russian space suit was a star sale at auction house Drouot, last February. Worn by veteran cosmonaut Dzhanibekov Aleksandrovich, it had been valued at €30,000-35,000 before excited bidders pushed its price up to €43,749.
In other space memorabilia news, an Apollo 11 training suit worn and signed by none other than Buzz Aldrin, the Second Man on the Moon, is also for sale.
Boasting an exceptional provenance, this rare and highly valuable suit is currently held by Paul Fraser Collectibles and can be viewed here.
