The two lots give fans of the zoo the opportunity to secure a piece of its history, while raising money for conservation and education charity Bristol Zoological Society, which owns the site in Clifton.
The items range from original zoo signage to animal sculptures, statues and Victorian benches.
All the money raised will help fund the creation of a new conservation zoo at Bristol Zoo Project near J17 of the M5, as well as the charity’s conservation work.
Justin Morris, chief executive of Bristol Zoological Society, said: “We know the former Bristol Zoo Gardens holds a special place in the hearts of so many people who visited or who were associated with it in some way, which is why we have taken our time to ensure any items of particular historical or sentimental value were preserved.
“With the launch of these auctions we hope people will take the opportunity to join us in celebrating our long history while also helping to fund the future, by securing their own piece of the gardens.”
