Alongside our main £40 'Lucky Dip' postcard sale we’re lucky enough to be able to run a separate, smaller Online Auction. The artworks consist of framed, fragile and larger-than-postcard-sized works, and pieces artists have specially donated to the auction to help raise extra funds for the Arts at the Charter School North Dulwich. 

The artists include: Tracey Emin, Norman Ackroyd, Maggi Hambling, Gillian Wearing, Jerry Dammers, Humphrey Ocean, John Keane, Gary Hume, Alessandro Raho, Edmund de Waal, Ishbel Myerscough, John Stark and Richard Deacon. Many of the artists have also donated Postcards to our £40 ‘Lucky Dip’ sale.

The auction in now live and runs for three weeks, ending on Wednesday 17th October at 9.30pm.

What is 32auctions? 32auctions is an Online Auction provider we are using to help run the auction.

When does the auction start and finish? The auction starts on September 26th 2018 at 8.30pm and closes on October 17th 2018 at 9.30pm.

Can I view the actual artworks before I bid? You can see images of the artworks on the 32auctions website but if you want to view them 'in the flesh' you can do so at the Secret Charter exhibition. This will take place at The Dulwich Picture Gallery (our venue partner) from 12.00 - 9.00 PM on Monday the 15th October, entrance £5.

What are the guide prices? Our guide prices are approximate and have been arrived at informally. The artworks have not been professionally valued.

What is extended bidding? The Secret Charter auction uses Extended Bidding which prevents 'sniping'. Sniping is the practice of placing bids, often via a computer program, in the last seconds of an auction without allowing a chance for other bidders to outbid the 'sniper'. The Extended Bidding option automatically extends the end time of an item by 3 minutes when it receives a bid during the final 3 minutes. This process repeats until no new bids are received during the final 3 minutes of the item bidding window or the auction has been extended for a maximum of 30 minutes beyond the original end time. When an auction is extended, you will see Extended Bidding messages displayed throughout the auction. 

So, in a nutshell, the auction officially ends at 9.30pm but if any bids are received on an item in the final 3 minutes, that item's auction end time will be extended for 3 more minutes, and so on, until there are no bids made in a 3 minute period, for a maximum of 30 minutes. This should make for a calmer and fairer end to the auction.

What is a proxy bid? A proxy bid is when you place a bid for the maximum amount you are willing to spend, then let the system bid for you up to that amount. You can also place bids manually (i.e. place one bid at a time). Explanations are available for the bid types by clicking the 'Help' icon next to each item on any auction page.

Why do some items have higher starting prices than others? An artwork has a higher starting price where the artist has placed a reserve amount on the item.

Will I be notified when someone outbids me? All participants should receive a notification when they are outbid. You will receive the outbid email only if your bid is the leading bid and then someone outbids you. You should also receive an email when you submit a bid, confirming your bid and letting you know if you are the leading bidder. If you are not receiving notifications, please check your spam or junk email folder.

How do I know if I’m the winning bidder? All winning bidders should receive a notification email from 32auction after the auction closes. If you are not receiving notifications, please check your spam or junk email folder. You can also log in to your account and click “My Items Won.”

What happens when there are two bids of the same amount on an item? Anytime the system receives two bids that are the same, the first bid entered into the system wins.


I won an item, how do I get my artwork? We are happy to post and package the artworks but due to the varied size and fragility of some of the pieces, a set price for delivery is not available. We will contact the winning bidders through the 32auctions website after the auction to discuss delivery or in-person collection. A separate payment will be necessary to cover any postage and packing.


How do I pay for my items? Payment is due immediately on receipt of invoice and must be made using 32auctions' online payment system. Winning bidders will receive a notification with payment instructions. Items must be paid for in full before being picked up.

What payment options are available? When the auction closes, 32auctions will automatically email winning bidders with notifications containing payment instructions. Winning bidders can click the payment button to pay online with a credit card or debit card.

Are refunds available? Exchange or refunds are not available. All sales are final.
