You’ve poured over the catalogue. You’ve become enchanted. Here’s how to acquire the item of your dreams.

The Auction:

When: July 18, 2023 at 11AM EDT
Where: Rennert’s Gallery, 26 W. 17th St., New York, NY 10011 (Union Square / Flatiron District)
And online at:

Our auctions move fast – about 125 lots per hour – and without a break.
Sales are final. Decisiveness is crucial.

Bidding Online:

Our primary platform is powered by Auction Mobility. You can access it directly here or through our website (click “View Lots/Register” or “Live Auction” on auction day). We encourage auction participants to use this platform as it offers a slightly lower buyer’s premium (23%) than Invaluable (25%).

To properly view the lots and navigate through the pages, please be sure to extend the width of your internet browser’s window.

  • You must confirm a Credit Card number before you can bid on any lot. Make sure to register a CC# before the live auction.
  • When bidding on our platform, you will be asked to confirm your bid.
  • When the auction starts on July 18 at 11am EDT, you can access a live video feed of the auction at
  • Download our free mobile app (Apple iOS or Google Android) and have full bidding immediacy and functionality wherever you may be on auction day.

Please note: Until the day of the auction, the bids shown online only reflect other internet bids made through our website. On the day of the auction, you will be bidding against people who bid in-person, by phone, by absentee, and through Invaluable. If you are unable to be at your computer during the auction, please be sure to leave your maximum bid amount online. Having the highest max bid online does not guarantee you as the highest bidder on auction day. Please keep in mind that bid increments affect your standing; a poster can possibly sell to another bidder for the same amount as your max bid.

1. Log in to your account. Tap on the auction you’d like to bid on.
2. To view the live auction, tap on a lot and tap on “Live Auction in Progress—Join Auction.”

Rennert’s Gallery / PAI imposes a buyer’s premium (commission) upon every winning bid (between 20% and 25%, see below for details).

Once the gavel descends, the sale is final. About one week after the auction, you’ll be sent an invoice including sale price, buyer’s premium, all applicable taxes, and shipping costs. When we receive your payment, we will immediately send your item.

  • Frames: If your purchased item includes a frame, we can ship it with or without the frame; in a poster tube, shipping costs are roughly $60 domestic U.S.; with a frame, average shipping cost is $250 domestic U.S. However, prices vary widely depending upon size and weight. We are also happy to frame any items purchased from Rennert’s Gallery / PAI. For an average-sized poster, without matting, prices begin at roughly $350. Please call us at 212-787-4000 with any questions.

We look forward to hosting you on Tuesday, July 18. Good luck!
