Book enthusiasts assembled at Old Windsor Memorial Hall to seek rare and collectible Observer Pocket Books.
Published by Frederick Warne, the books were released between the 1930s and 1980s, covering all manner of subjects, from world flags to kitchen antiques.
The event at the Hall in Straight Road on Saturday was organised by the Observer Pocket Book Collector's Society.
Peter Impett, from Shepperton, hosted the sale.
He explained that many fans are big-kids who first got the books as they were growing up.
The 'holy grail' of pocket books is the glossy covered edition on dogs, which can sell for a three-figure sum.
Peter has been collecting for 10 years. His a fan of the concise books because of their convenience.
He said: "I often find I'm sat watching the TV and a quiz will ask 'what's the flag of South Africa', and I've got the Observer books right there."
